Below is my comment to AA on a code share flight operated by IB.

3/31/11 AA Flight 5657 from BOS to MAD was cancelled by IB more than 2h before departure. IB did not notify AA or put the flight into cancellation until after departure time. All the while there was a a line of the entire flight waiting more than 2 hours to be rebooked which they were doing yet AA showed the flight "on time" or "delayed." IB is lying to AA. IB is cancelling flights because they haven't sold enough tixs and making customers wait for hours because they are trying to rebook with only one person who has the skills and/or authority to change tixs. They also do not recognise priority access.

When we finally got to the AA lounge another passanger said this is common practice with IB and BA. They cancel flights at the last minute if not enough seats are sold.

Time for AA to put a stop to this practice by the one world airlines or stop code sharing these flights.
