Ok, agreed on pretty much all counts there. Twitter is very much not obligated to pass along any random person's terrible views (and thanks for the disclaimer; no interest in seeing that argument again). If Trump decides to conduct official business there, they aren't quite facing compelled speech because they can (in theory) ban him; the outcome we'd hopefully get is that his official speech is restricted, but Twitter is free to host him or not. I suppose at this point the only question is whether a government-proxy rationale applies to airports in this specific case, since I definitely agree that Kayak or Travelocity couldn't be required to accept these ads on their site.
