I’d love to hear some of the answers given to these types of questions. If honesty and transparency were in play, most people would say 1) your bases fit my situation 2) you called before delta or American. I wonder how much smoke is required to be blown up the CP’s ass in order to get a recommendation for an interview? Anyway, play the game and sound like United is the end all/be all, and you’ll do fine. Good luck.
