American isn’t changing fare-publishing

EF1American Airlines’ roll-out of a new bundled fare structure this week has created some confusion among frequent fliers about what the change means to the way they book tickets. They have nothing to worry about — at least for now. American is not changing the decades-long practice of how fares are published on an airline tariff, and fears of a lack of transparency are misplaced.

You can still see in which booking class your ticket will be issued, though it’s indeed a bit confusing how exactly one would know the difference between the three new fare types by looking at that booking class, which could be the same for all three fares. So let’s break all this down and try to make sense of it.

First, what has American changed? It has bundled products and services that airlines have been unbundling for a few years, though some of those extras like certain seats are still sold separately. When you search domestic fares in the contiguous 48 states on its website, you now get three tabs: lowest fare, refundable (both coach) and Business/First Class. The default tab is lowest fare. In that category, there are three types of fares, as shown below for a one-way trip from Washington to Los Angeles…

U.S. fares now filed four times a day

North American airfares are now published four times a day during the week, after the Airline Tariff Publishing Company (ATPCO) added earlier this month a filing feed at 4 p.m. Eastern time to the already-existing feeds at 10 a.m., 1 p.m. and 8 p.m.

This means that, at any of those times, a certain fare can be put on the market, changed or pulled off the market. It also means that a fare’s entire lifespan can be as short as three hours. The 4 p.m. feed had been planned for months, as I wrote in my book “Decoding Air Travel.” Although the airlines update their data 24 hours a day, ATPCO sends that data out to Global Distribution Systems (GDS), which are used by airlines and travel agencies to book flights, four times a day during the week. On weekends, there is only one feed at 5 p.m. ET…
