AA Timetable Error?

Sat Jul 12, 2014 6:12 am

In their most recent PDF timetable (Effective July 8, 2014), there seems to be an error of some sort...

For almost every flight, the regular schedule discontinues on Aug 18, then the same flight changes to "234" frequency (Tue,Wed,Thur), effective Aug 19. It's not limited to AA or US operated flights, or any specific regional, but its not true for EVERY flight. However, if you aggregated all the info, I'm pretty sure it would show just a few flights a day on Fridays-Mondays, starting Aug 19, which just doesn't make any sense.

If you try to book any of these flights on Friday, Aug 22, they are available...so it's definitely a printing error. This simple question is...what could cause something like that?

I believe this happens -- and it is not uncommon on AA or other cx timetables, such as AS -- as part of a set-up to the next big schedule adjustment.

As you mentioned, it looks like August 22 will be the next schedule change for AA and this July timetable lists, for whatever reason, that 3-day "gap" separately. (As you probably have noticed, there are many instances where a flight will be listed twice, discontinued and effective, but the 2 lines displayed are identical; I figure that there are some internal scheduling changes taking place that don't actually affect the data that we see.)

I can say that when I see this sort of thing in a timetable, the first thing I do is look at a couple of other random routes (in major markets.) If I see the same thing showing for flights there, it means it's some sort of schedule-change transition. And I ignore it!

Thank goodness there are some airlines that still produce timetables like this. They give a much neater and clearer picture of a carrier's actual schedule than those put out by, say, UA, and DL, etc., and of course, than the cx that don't publish any sort of timetable at all -- such as F9, VX, B6, WN... But in reality it's all about how the airline actually schedules flights -- the timetable simply reflects how the scheduling department does things.

Customers are only interested in the carrier's service on the route they're planning to fly which can easily be found. Probably saves a lot of money not producing a PDF timetable. I miss timetables as historical documents but I understand the reasons for dropping them.

Not quite sure where the savings would come from? I'm willing to bet these PDF timetables are automatically generated. If not, sure seems like a waste of someone's time.
