Minimum information required to file a fare in a GDS
score:6
Accepted answer
The minimum information to supply will be something like this—
- A name for your fare, where the first letter is the prime booking class of the fare (you can just give it a one letter name if you wish). This is known as the "fare basis".
- The cabin into which the fare books [although this can be inferred from the booking code, actually you also need to know which booking code books where, and this varies by airline].
- The city pair on which the fare is filed (e.g., LON to AKL).
- The price of the fare (prior to taxes, fees and surcharges).
- Whether pricing units constructed under the fare must be round-trip or whether one-way units are allowed.
- A minimum set of fare rules, including a human-readable description of the fare under the Fare Applications category, but probably the other categories can be left empty. That said I have never seen a fare with an empty Combinations category.
- Either a maximum permitted mileage ("MPM") for the route constructed under the fare or a specified routing in the fare routing table.
- Whether the fare may be autopriced (that is, whether tickets can be issued using this fare by a computer), or whether a human must be involved to do the ticketing.
A good example of a short fare with minimal information is any "YY" fare. These are generic fares filed by IATA instead of by an airline, but every IATA-member airline is supposed to accept tickets using these fares printed on neutral ticket stock as valid for transportation. Therefore these fares effectively set a price ceiling on many routes. The original intention of YY fares is to relieve airlines of the burden of setting up fares between unusual cities, but since the process is all automated nowadays, such reasoning no longer applies. Indeed, many airlines (LH, BA at least) no longer accept YY fares as valid on their services, and many file higher prices than the YY fare (such as BA on London-Dubai). Anyway, here is a YY fare list on London-Nairobi. You can see most of the columns are blank, indicating no restriction applies.
Fare Basis Airline Booking Trip Type Fare Cabin Effective Expiration Min/Max Advanced
Class Date Date Stay Purchase Req
YIF YY Y One-Way 1708.00 (GBP) E
YIF YY Y Round-Trip 2440.00 (GBP) E
CIF YY C One-Way 3308.00 (GBP) B
CIF YY C Round-Trip 4726.00 (GBP) B
FIF YY F One-Way 5344.00 (GBP) F
FIF YY F Round-Trip 7634.00 (GBP) F
Picking the oneway CIF fare, the rules of this fare are as below. You can see that most of the categories have been left blank, but some have been filled out. In principle you could also leave the Discounts and Sales Restrictions categories blank.

This probably represents something close to the minimal information you could supply in a rule. Finally as I say we should look at the fare routing table. Again for YY CIF on LON-NBO, you can see the only restriction is that the total route length (in each direction) between London and Nairobi should be a maximum of 5089 miles, and each flight should be constrained to be within the eastern hemisphere.

If you don't file a routing table, someone will construct a route going all over the world before eventually ending at the destination, and you'll have to compensate all the other airlines who offered carriage under your fare. So be sure you get that right.
