Canceled flight after hours of sitting on the tarmac and then waiting for several more hours to get a hotel and rebook a flight that was going to be days later. Don’t book the flight unless you have pilots to fly it. Not reimbursed for all meals, travel, and certainly not time. American Airlines lost a customer for life on this one. Only one person out of dozens from American seemed the slightest bit concerned about the welfare of the customers.
