These comparisons are invalid. Complaining about service is one thing, complaining about airplanes that are in the news almost every day because of the constant engine failures, evacuations and the like is an entirely different arena. Delta or United pilots are not being sent TDY for over a year or unable to be paid correctly or being terminated for performance because of mishandling the chronic crappy maintenance or training (their training department that was shut down by the FAA). They won't complain about feeling like their flying license is in jeopardy, every single day being set up to fail because of the cheapest and minimalist approach to everything and non existent support from their bosses.
