I booked an AA flight, LHR-JFK, BOS-LHR, using Citi thank you points for a friend. Passenger is platinum member on AA.
Due to unusual traffic he arrived at LHR 45 min before flight. He was denied boarding and they wouldn't book him onto another flight until he spoke to the travel agent. He tried haggling with them and in the meantime I called thank you travel. After a long hold they told me that AA at LHR have cancelled the entire itinerary, so nothing they can do.
Passenger had to rebook (with BA) for almost double the price plus he had to pay for his second suitcase which he would have had free on AA due to his elite status.
Who do I write to? AA? DoT? Citi Thank You?
And what can I expect?
