I wonder how much you could get out of their support as an apology, ie free flights and so on? I never really try that, but I hear some people extract bonus offers routinely.
Apology? Mwahahaha! What happened was that they sent me an email saying the electronic ticket would follow by email within 24 hours. This was on a Friday for a Monday morning flight at 8:00. When no ticket arrived by Sunday morning, I called them to discover their office was closed. I called again at 5AM on Monday morning and they were still closed, so I waited until their office opened at 8:00.
Wrong move. They charged me for the flight, saying that even though they promised an e-ticket and didn't send it, and even though their offices were closed, I should have shlepped out to the airport where the airline would have resolved my problem. I appealed to Visa but lost.
