My recent flight from Buenos Aires to Dallas was cancelled due to mechanical problems about 3.5 hours after the scheduled departure time. AA provided overnight accommodations and rescheduled our flight to the same time the next day. I managed to rebook myself on an earlier flight the next day and called the taxi company AA told us to use for the return airport transportation. However, they did not come pick me up. Also, during the whole ordeal, AA did not provide us with any water or food vouchers. When I inquired about the reimbursement process at the Buenos Aires airport, the AA staff shrugged me off and did not really want to deal with me. This was my first international flight on AA and the overall experience was a major service failure for me on many levels. My friend was on the same flight 6 weeks ago and it too got cancelled for mechanical problems. I just received a response to the online complaint I submitted. AA is offering me a $300 e-voucher for the inconvenience. Is this considered adequate compensation for a cancelled international flight?
