First, here is a basic lexicon for navigating the discussions on the SQ Board. When a part of the definition refers to another item on the list, I have italicized that portion.

BTC: “Book the Cook”; a service for premium class passengers who are departing from a number of cities, which allows them to pre-order a main dish for their flight. For more details, see the Raffles Class section of the FAQ

Changi: SQ’s home base; Singapore’s airport

Connexion (by Boeing): wireless broadband service being rolled out across the fleet. It's currently available on the SIN-LHR, SIN-SYD, and occasionally on JFK-FRA-SIN. For more details, see the FAQ section on economy class travel

Double-Dipping: The option of crediting Raffles and First Class miles to another FFP while at the same time having those miles and sectors recognized by SQ towards PPS Club status. For more details, see the FAQ section on the PPS Club

Executive Economy: the economy class in the nonstops, featuring more legroom (37” seat pitch) than normal SQ economy class flights; more KrisWorld options; a more extensive menu; in-seat power; and a socializing area in the back of the cabin

Jubilee: SQ’s term for the Boeing 777s in their fleet

KrisFlyer: SQ’s frequent flyer program; see ‘Doubled-Dipping’ if you’ll be flying Raffles or First Class a lot

KrisWorld: SQ’s in-flight entertainment system (movies, TV shows, CDs, games)

LeaderShip: SQ’s original term for the Airbus 340-500s that fly nonstop between SIN and LAX and between SIN and EWR. The name has been dropped, in line with a new policy of not coming up with nicknames for the plane models; there are some who are saddened by the demise of the practice of nicknaming planes

Lifetime PPS: A PPS member who had accumulated 1,875,000 PPS miles or 1,000 PPS sectors and therefore no longer needed to worry about re-qualifying. This status will be abolished after 31 August 2007.

LPP / LPPS: Abbreviation for a Lifetime PPS member

Megatop: SQ’s term for the Boeing 747-400s in their fleet

Nonstop: the short-cut way of referring to the A345 flights between SIN and LAX or SIN and EWR

PITA: the, um, affectionate term for PPS members who test the service ethos of SQ staff; stands for ‘pain in the a**’ (or ‘a***’, depending on the variant of English that you use)

PPS / PPS Club: the true elite tier in the KrisFlyer program, achieved by flying 50,000 PPS miles or 25 PPS sectors within a 12-month period*. PPS status grants *G privileges, and quite a bit more. See the FAQ section on the PPS Club

*Note: This method of qualifying will hold only until 31 August 2007. After that, new value-based qualification requirements (discussion in this thread) must be met.

PPS Miles: miles flown in: (1) SQ Raffles Class; (2) SQ First Class; (3) Silkair Business Class; (4) Business or First Class of SQ-numbered (i.e., code-share) flights

PPS Sector (also sometimes shortened to ‘sector’) : The second way (the other being miles) of determining whether you have qualified into the PPS club. It’s like a segment count, but you get more credit for longer journeys and for flying First Class. Qantas’s SCs and BA’s tier points are analogs. The exact assignment of miles flown to number of PPS sectors earned is shown here. The sector must be earned in the classes specified in the definition for ‘PPS miles’

QPP / QPPS: Abbreviation for a KrisFlyer member who has qualified into the PPS Club

Raffles Class: SQ’s Business Class

SIN / Bali Do: The major events for SQ flyers and kindred spirits. Organized a couple of times a year and planned through several pages in the CommunityBuzz! Forum on FT. Mucho fun for everyone.

Singapore Girl / Boy: SQ’s cabin crew; the centre of gravity of SQ marketing

SKL: Silver Kris Lounge; SQ-operated lounges

SkySuite: SQ’s First Class seat-bed, available on all the Megatops (but not, it must be noted, on the nonstops)

Solitaire: A PPS member who has accumulated 500,000 PPS miles or 250 PPS sectors*

*Note: This method of qualifying will hold only until 31 August 2007. After that, new value-based qualification requirements (discussion in this thread) must be met.

SpaceBed: SQ’s Business Class seat, available on all but one of the Megatops and some (i.e., the 777-200ERs) of the Jubilees

TPP / TPPS: Abbreviation for a Solitaire member

Turnaround: A trip taken purely to maximize miles, maximize sectors (PPS, that is) or take advantage of lower prices when tickets are issued from certain cities. If you do a turnaround, you have no intention of exploring the city to which you've travelled: your flight lands and you attempt to turn around and leave on the very next departing flight. It's one of those practices (like not having to look up the departure and arrival times of specific flight numbers) that signify your membership in the ranks of hardcore frequent flyers

Wisemen 2000: Wisemen 2000 exists only in one aircraft now: B747-400 9V-SMT. The rest of the fleet either have Wisemen 3000 or just plain KrisWorld

Wisemen 3000: SQ’s AVOD system, available on all long-haul flights but, unfortunately, not necessarily on all intra-Asia flights. See the FAQ section on economy class travel for tips on how to use the remote control to skip the ads at the beginning of each selection

More generally, there are abbreviations, such as airline codes and fare booking classes, that FTers often take for granted during their discussions. Two useful threads for these are, respectively, Kiwi Flyer’s *A Useful Reference Links and *A Booking Classes.
