<<Disclaimer: Verify this information before applying it to your situation.>> Even an airline that seems to be doing pretty well can cause unexpected problems, and I learned the hard way to be prepared. I've done reasonably well on a several airlines--an occasional bagel or package of croutons on an otherwise gluten-free meal, but nothing that would present a problem to anyone capable of recognizing obvious blunders, and no ill effects afterwards. So I wasn't carrying GF food on a cross-country return flight (on American I think--but it might have been Delta) this July, San Francisco to Raleigh-Durham, that was cancelled at the last minute, with passengers all rerouted on later flights. When I asked the attendant rerouting us about my gluten-free meal, she tried to help but obviously had no training in what to do--didn't know what one was, finally figured out for herself that that's what "GF ML" means in computer records, and did call the caterer, who told her they'd see what they could do. What they did was nothing al all--not even an attempt at a GF meal, or any alerting of crew that I needed special food of any sort. Even the snack was pretzels instead of nuts. (They did serve nuts on the last leg of the flight, and sympathetic friends showered me with cashews.) I'll never again fail to carry food for long flights, even on airlines I trust.
