What precisely does a "flexible" ticket mean, in terms of the commitment of airline to the ticket holder? If a business class or high price economy ticket "allows changes" but the flight to which the passenger wants to change is sold out, or there are other people holding "flexible" tickets and wanting to change to the same flight, what is the passenger entitled to?
