<<Disclaimer: Verify this information before applying it to your situation.>> I just called Delta and complained about the fact that they don't know what gluten free meals are. I was told I was the first person in 15 years to complain.I therefore suggest that we the Celiac community bombard them with phone calls to get their act together and find out what g. f. means. The toll free no. is 1-800-221-1212 . Ask for customer relations and tell them loud, clear, and often. If other airlines can do it why can't they?
