Strongly leveraged / plagiarized from premerger United Airlines Forum Glossary

While FT has a general glossary, there are terms commonly used in this forum that are unique to United or very frequently used in this forum. I would ask we keep the dialogue here informative and neutral in tone.

Links to more in-depth discussion of common topics can be found in United MileagePlus Master Wiki
Airport city codes can be checked by Googling or FT airport code lookup

Frequent Flier Terms:
  • BIS: Butt in seat miles (miles actually flown).
  • Base miles: This is normally the actual flight miles. Credited miles will be based on base miles (as a percentage). UA elites will have 500 mile minimum on UA/UX/COPA flights and selected partner flights.
  • CPM: Cost/Cents per mile -- cost in USD$ * 100 / miles. It is used as a mileage normalized measure of value / cost.
  • PQM: Premier Qualifying Miles - Miles that count toward qualifying for status in the MP program. PQMs are not redeemable for award travel. Previously called EQMs. PQM are earned based on flight miles.
  • PQS: Premier Qualifying Segments - Segments that count toward qualifying for status in the MP program. PQS are not redeemable for award travel. Previously called EQS.
  • PQD: Premier Qualifying Dollars - Dollars spent on travel that count toward qualifying for status in the MP program. In simple terms, this metric includes base airfare, E+ access purchases and carrier surcharges - does not include taxes and most "extra fees." PQDs are on calculated for members with a U.S. mailing and are not redeemable for award travel. PQDs started in 2014.
  • FPQM: Flexible Premier Qualifying Miles - These are Premier qualifying miles that can be stored and used years afterward. FPQMs are earned by use of the Chase/United Presidential Plus credit card. 1000 FPQMs are earned for every USD$5000 in credit card spend. (The Presidential Plus credit card is no longer available to new applicants.)
  • XFPQM: Expiring Flexible Premier Qualifying Miles - Originally, FPQMs had no expiration date. Now FPQMs can expire. That expiration happens up to 39 months after being earned.
  • NXFPQM: Non-expiring Flexible Premier Qualifying miles - They never expire.
  • MP: MileagePlus - United's name for their frequent flyer program. The space between Mileage & Plus was removed in 2012 in the merger of United and Continental.
  • MR: Mileage Run - A trip taken for no other purpose than to accrue miles (or segments) to attain or retain status. An avocation seemingly peculiar to many FTers.
  • RDM: ReDeemable Miles - Miles that count toward award tickets and upgrades. The number of RDMs has no impact on status qualification. RDMs, for UA flights, are based on PQDs.

Mileage Plus Status levels and terms in generally ascending order: see Premier benefits and more or Guide to United's Premier Status Levels
  • GM: General Member: No elite status. Just collects small amounts of miles (by FT standards, of course)
  • Premier Silver, PS, or just Silver: 25000 PQMs or 30 segments in a calendar year (and unless waived USD $2,500 $3,000 {2015/16} PQDs). Was called 2P, Premier in premerger UA program.
  • Premier Gold, PG, or just Gold: 50,000 PQMs or 60 segments in a calendar year (and unless waived USD $5,000 $6,000 {2015/16} PQDs). Was called 1P, Premier Executive in premerger UA program.
  • Premier Platinum, PP, Plat, or just Platinum: 75,000 PQMs or 90 segments in a calendar year (and unless waived USD $7,500 $9,000 {2015/16} PQDs). This level was unique to premerger Continental and was their highest earned level. Some refer to this level as 0P, in the spirit of the pmUA labels.
  • Premier 1K or just 1K: 100,000 PQMs or 120 segments in a calendar year and USD $10,000 $12,000 {2015/16} PQDs (no waiver for this level). 1K is the highest level that can be "earned." This level was unique to premerger United.
  • GS: Global Services or sometimes UGS -- A special program run by UA to bestow higher benefits and prioritization to travelers with significant annual spend. The exact terms of this program are not disclosed by UA but terms like top 1% of elites or USD$40K annual spend with >40 cpm have been rumored. A GS can alternatively receive status based on their position to impact travel or based on contracts with UA. GS have all 1K benefits plus more and are prioritized above 1Ks. This program came from pmUA, however just prior to the merger pmCO had introduced a similar Presidential Plus designation.
  • 2K, 3K, etc. : Informal FT terms to indicate those that have received 200,000 or 300,000 PQM in a year. Not formally used by UA and carries no extra benefits (although will earn additional RPUs / GPUs).
  • MM: Million Mile Fliers- Not a status level. Folks who fly multiple million lifetime miles received life time status (1MM= Gold, 2MM=Plat, 3MM=1K and 4MM=GS) and the ability to match another person to their annual status level. Lifetime miles are the lifetime accumulation of BIS. In 2012 as a part of merging the Continental and United programs, UA flyers received prior years' credits to match the Continental policy of using PQMs. However, going forward, new earnings are based on BIS miles.
  • -lite: An MP member that obtains a status level through promotions or other non-flight related activities.
  • Status Match: UA may temporarily grant status based on status in a competitor's frequent flier program. Usually this will be accompanied by a challenge - fly xx miles in the next yy days and if successful maintain status for a longer period. The point is to recruit new customers. Generally, UA will not poach members of other Star Alliance frequent flier programs.

Merger-Related Terms:
  • PMCO / PMUA: Pre-merger Continental or pre-merger United - tends to be used in reference to practices / policies used by the previous airlines.
  • sCO / sUA: Subsidiary Continental or subsidiary United -- until the merger is finalized, certain things (aircraft, flight crews, ...) are not yet fully integrated Tends to be used in reference to practices / policies / employees / aircraft by the group they are still segregated in. sCo uses UA flight numbers 1 - 199 & 1000 - 1299, and sUA uses 200-999. (exception is sUA 739s which use flight numbers in the sCO range ) flight number deviations started occurring in late 2015

Other pre-merger terms:
  • Battlefield Upgrade: A pmCO term for an upgrade at the gate and/or at the last minute
  • Ted: A pmUA aircraft config used on "leisure" routes to compete with the low-cost carriers - Ted flew single class A320s and was discontinued long before the merger. RAR!
  • Infinite Elite: A pmCO term for a relatively few CO OnePass FF program Elite level members. Those earning this status were required to earn top tier level for 5 consecutive years in the early-mid 1990s. Members were only allowed to enter for qualification consideration for just a couple of years. This earned them Infinite Elite status with the guarantee of Lifetime top Elite level status without ever needing to requalify. At first, Gold was the top tier, requiring 50,000 miles. This was then changed to 60,000 miles. Then, CO added a Platinum level, which required 75,000 miles. When CO and UA merged, Infinite Elite members became Lifetime 1K members of MP. There are still relatively few remaining, as many have advanced in their careers and no longer fly as much, or have retired or are limited in flying for health or aging reasons. Many are proud of the title as they stuck with CO during the dark days of bankruptcy.

Ticketing & Fare Classes:UA paid fare hierarchy: F, A, J, C, D, Z, P, Y, B, M, E, U, H, Q, V, W, S, T, L, K, G, N

United Cabin names:
  • Polaris First GlobalFirst / GF: The front cabin of a 3-class cabin aircraft - only offered on sUA aircraft. Being phased out.
  • Polaris BusinessFirst / BF: The front cabin of international 2-class cabin or the middle (business class) cabin of international 3-class cabin aircraft (typically with lie flat seats). BF was coined by pmCO since Continental did not have 3-class cabin aircraft prior to the merger.
  • International Business: The front cabin of international 2-cabin (typically with domestic style F seats).
  • First: The front cabin of domestic 2-class cabin (wide seat with more pitch then economy).
  • Premium Plus (PP / P+) -- United's version of Premium Economy. Considered a separate cabin, separate fare class, better seat and service than economy
  • Economy (Y / E-): Standard economy seats. Sometimes referred to as "Economy Minus."
  • Economy Plus (E+): trademark name of UA economy seats with 3 to 5 inches or more of additional leg space but otherwise the same seat and services as regular economy. Access is reserved for elites and companions (at booking for Gold or higher and at T-24 for Silver) or for those paying an access fee, or for overflow from regular economy.
  • Basic Economy : A high restrictive purchase option for economy introduced in 2017. This purchase option has no advance seat selection or adjacent family seating, only one personal size carry-on, no check bag allowance, no refund or changes allowed, no upgrades, no E+ (purchased or based on status), no mileage earning except RDMs. Elites / credit card holders will still have a bag allowance and earlier Boarding group.

    Polaris was a new branding term introduced in late 2016 -- the entire premium travel experience was branded "Polaris" -- including all the lie-flat international cabins, new high-end Polaris lounge (and eventual removal of the GFL), new amenities (gel pillows, blankets, PJs, ...), enhanced food service plus new premium cabin all aisle access seat to be slowly rolled out. The use of the same nems for cabin / service level and seat created some confusion as the seats good be the BF style lie flat or the newer all-aisle access seat.

Flight operator terms:
  • UA Metal: a plane that UA(/UX) operates. The flight number could still be that of another (Star Alliance) carrier - this is called a codeshare. This has a bearing on earned mileage and other MP benefits.
  • Mainline: A reference to aircraft run by United proper rather than the commuter lines. The smallest mainline aircraft is larger than the largest UX aircraft.
  • Premium Service (p.s.) Transcontinental Service: A set of planes which operate exclusively between EWR JFK and SFO or LAX and in 2017 SFO-BOS. It is 2-class plane with lie-flat seats front cabin (occasional substitution 3-class). The premium cabin meal service is enhanced. These were the first UA planes with WiFi.
  • UA: United Airlines
  • UX, UAX: United Express - Commuter flights using smaller RJ, EX or CRJ planes, operated by contracted third-party operators. Mostly standard UA benefits and policies but some minor deviations.
  • *A: Star Alliance - a group of airlines which jointly participate in the MP program to some degree. Some elite benefits (mostly Gold and higher) - bag allowance, elite check-in & security and early and lounge access
  • *S: Star Alliance Silver - Star Alliance status extended to UA MP Silver or the designation of partner Silver level on UA.
  • *G: Star Alliance Gold - Star Alliance status extended to UA MP Gold or higher (Plats, 1Ks, GS) or the designation of partner Gold or higher level on UA.

Upgrade Terms: see Upgrades overview
  • CPU: Complimentary Premier Upgrades -- Potentially unlimited upgrades on most domestic routines and some international (typically those without BF/GF) UA/UX operated flights. Will not clear until close to departure - with clearance windows in advance of travel based on elite status. GS-5 days, 1Ks-4 days, Plats-3 days, Gold-2 days and Silver-1 day. Previously called UDU (Unlimited Domestic Upgrades (pmUA)) [prior to UDU, pmUA used e500s -- 500 mile upgrade certs] or EUA (pmCO). ["Elite Upgrade Automation" remains the backend process by which upgrades process at regular batched intervals. Thus, one may still refer to an EUA sweep.]
  • GPU: Global Premier Upgrade - an instrument that allows the upgrade of a single cabin level of an entire day's itinerary as long as it doesn't backtrack or have a long connection. Most useful for international travel and can be requested / cleared any time after booking if upgrade space exists. On non-CPU eligible routes restricted to certain fares (such as W or higher economy fares). Only usable on UA operated flights plus COPA and LH. Previously called SWUs.
  • RPU: Regional Premier Upgrades - like GPUs but limited to CPU eligible routes plus p.s. & EWR/IAD/IAH-Hawaii routes. Inherited from pmUA where they were called Regionals / CR-1 / HK50 / HK49.
  • MUA: Mileage Upgrade Award (an upgrade award using miles and copay). Copay is waived for full fare tickets and elites on most domestic routes.
  • Instant Upgrades / YB{M} upgrades: On CPU-eligible routes elites on Y or B fares and 1K/GS on M may (space available) request one cabin upgrade. Does not apply to non-elite companions.
  • YCA: Negotiated government fares which book into the Y level and which some FTers speculate contribute to poor upgrade rates out of some airports (especially the IAD hub).
  • -UP upgrades: -UP fares have economy fare basis but will book into domestic F when available. There may be issues in IRROPS if space is not available and these may be treated as economy tickets.
  • UFC: Upgrade For Cash - cash offers to upgrade 1 or 2 cabins on united.com or during check-in.
  • PCU:- Premium Cabin Upsell (time of purchase upgrade) was pmUA term
  • TOD: Tens-of-Dollars - cash offers for upgrades that seem unusually low.
  • Gate List: UA makes available starting at check-in the gate upgrade prioritization list. This is the only public information on the waitlist and only shows those that have checked-in, so ordering can change as others check-in. The pre-gate waitlist is "slightly" different and is not publicly available and agents are told not to release that information.
  • Expert Mode: a feature on united.com that allows one to see the available inventory classes including upgrade and award inventory.
  • REV/PR1: Applies to day of flight and when traveling on a First Class/Business ticket (revenue or award), but holding a Business/Economy Class seat (due to no F seats in your booking class being available), folks on this list have priority to be assigned any available seats. On pmUA this was called FFCC.
  • op-up: Operational Upgrade, an upgrade provided to a traveler by a United Gate Agent (or other airport personnel) without the need for an upgrade instrument. This is typically done when seats are needed in the class of services that you are booked in, and seats are available in a higher class. For example, if you are booked in Y and it is oversold, you can be moved to C if on a 3-cabin flight or F if on a 2-cabin flight. This is typically offered based on status, so the higher the status the better the chance, but you never know...
  • Double upgrade: The rare occurrence where you are booked in Y, and find a way to upgrade to C and then again to 3-class F. A rare but happy occurrence! You cannot use upgrade instrument to do a double upgrade but a cash / UFC can be offered on an instrument supported upgrade. Another situation is an op-up on a regular upgrade.
  • IDB: Involuntarily Denied Boarding. This is when a flight is oversold and a passenger is told that they no longer have a seat on the flight. The passenger is due compensation and rebooking per DoT regs.
  • VDB: Voluntarily Denied Boarding. In this case, a passenger willingly gives up their seat on the plane in exchange for compensation and rebooking on another flight (or sometimes not, if on a mileage run and the compensation is more valuable than the miles). Compensation / terms are negotiated with GA.
  • Downgrade: When a passenger who was upgraded is told that they are no longer upgraded (or they find out at the gate about it) because of either a plane switch (so less upgradeable seats) or other factors. Affected passengers are due compensation (refer to GG OVS DOWNGRADE).

  • GFL: Global First Lounge / International First Class Lounge (IFL)
  • Mr. Easy Chicken, Easy Chicken, Mr. Chicken, Mr. Easy: Various terms for the Easy Check-in kiosks in airports.

Personnel Terms:
  • $MI/J or SMI/J: Jeff Smisek, past United Chairman and CEO, left mid-2015. The style comes from how names are reflected on the upgrade and standby lists, which carried over from PMUA. Replacing the "S" with a dollar sign generally is regarded as a pejorative, reflecting post-merger degradation of service on both sUA and sCO sides.

thanks for the improvements.

Have done the formatting change suggested by goalie.

Corrected the missing IAD from list of Hawaii flights requiring RPUs caught by love_to_travel

Added a few more thoughts, including "Lounge Dragon" suggested by DBCme

Still a work in progress.

Many thanks

Thank you for this WineCountry. Excellent reference.

Could I ask about PNR Terms? Are these things something passengers see or have access to or just behind the scenes on a mysterious screen that United staff see or use?

perhaps further define GPUs and RPUs in terms of how they're earned? here's copypasta from .bomb:

Premier members will earn two Regional Premier Upgrades upon meeting all qualification requirements of Premier Platinum status, plus two more upon meeting all qualification requirements of Premier 1K status. An additional two Regional Premier Upgrades will be awarded for each 25,000 Premier qualifying miles or 30 Premier qualifying segments earned thereafter.

Added FPQM, XFPQM and NXFPQM. Although the Presidential Plus card is no longer offeredas I noted in the wikithousands of us still have that card and therefore these terms remain relevant, methinks.

RNE, giving the go-ahead to edit my edits. I'm in the dark on Waikiki and can barely see what I'm typing.

Since you mentioned it, how about adding

PPlus (for the Presidential Plus credit card)
MPE (for the MileagePlus Explorer credit card)
MPC (for the MileagePlus Club credit card)

Any other credit cards worth mentioning?
