Where does the KVS tool get its data and is KVS authorized to provide this data in the manner it is presented?

The tool is known to access a variety of web sites, many in a manner that is not authorized. Please see the next section of this Wiki for a list of sites believed to be accessed and their data access policies (where known).

Additionally, under some conditions the tool appears to access sites via a KVS-operated back end. This means that the tool is not just a 'web browser' that runs via a user's machine. No detailed public information is available about how this works or whether any of this back-end access is authorized.

I'm not quite sure what I should be looking for in the way of my likelihood of an upgrade to business class....J, C, D & I ......is that correct?

Many thanks

You should be looking at Award/Upgrade Availability (http://Help.KVSTool.com/#QF), as well as Availability in the lowest regular Business Booking Class (I).

Delta -UP Fare and KVS

I'm having a difficult time correlating DL online fares with KVS data. Specifically, I have purchased several H-UP fares but cannot find the same fare with KVS.

For Example (by searching/purchasing from DL.com):

18 JUN FLL-ATL
22 JUN ATL-FLL

Selected REFUNDABLE and H. Fare paid was $725 which I then -UP'd by calling DL reservations. No additional charges.

If you select the same itinerary, buy only select H and NOT refundable, the fare is $699. When you call to -UP that fare, there is a charge of $25.

I cannot find either the $725 nor the $699 fare using KVS.

I'd like to be able to search KVS for other routes fishing for -UP fares. Surprisingly, the full Y fare, over $1,000, on this route is not upgradeable?!?!

Your assistance is appreciated!

There is no Fare difference: $678+$21 in Taxes is $699 and $704+$21 is $725.

It is just a code that identifies a particular Fare -- please refer to the Fare Rules for all the details.

To be a bit more precise: the 1st letter generally refers to the fare bucket which the fare books into. The rest of the code normally summarises the fare in some way - but each airline uses their own system for this. If you regularly look at the fare basis codes for a specific airline, you may be able to identify the patterns.

For example, looking at AF (and KL) (incomplete extract):

[KVS Availability Tool 6.9.9.R3/Diamond - ATP: Fares/FC/US]

Code:

CDG  Paris Charles De Gaulle FR [LFPG]
NYC  New York Metro NY US = JFK LGA
R/T  

Carrier    From    To    Fare      Cur   Total     Q    YQYR  Fare Basis

AF         PAR     NYC      1772   USD      2123         351  UHSFFR
AF         PAR     NYC      1818   USD      2169         351  SLLSFR
AF         PAR     NYC      1900   USD      2251         351  SKLSFR
AF         PAR     NYC      2067   USD      2418         351  SHLSFR
AF         PAR     NYC      3219   USD      3570         351  SFFFR

we can deduce that:
1st letter = fare bucket
2nd letter = seasonality (L = low season, K = shoulder, H = high; not present for fares with no seasonality)
3rd, 4th letters = degree of flexibilty (SF = semi-flex, FF = fully flex; not sure about SB, SR or LS)
5th, 6th letters = country of origin (FR = France in this case)

For some airlines, the maximum validity will be included in the fare basis code (eg: 3M = 3 months, 1Y = 1 year, etc)

For DL, I'd guess that the number in the middle is the advance purchase requirement (eg: 21 = must be purchased 21 days in advance). However, I don't have sufficient experience to be able interpret the rest of the DL fare codes yet.

As has been said, full information is contained in the fare rules, in any case.
