Not a quality. Those were just lame reasons for choosing an airline in this current market.
As for the second part, say I am a mid 20s guy and I love the west coast. Why shouldn’t I take DL for SEA and LAX, or UA for SFO and LAX? Culture, 737, routes doesn’t cut it.
I can’t believe that you’d either ignore, or worse, disregard one of the more important career aspects: seniority and upward movement from retirements. 3400 pilots today and how many retire the next 10 years? 600-700ish? The big 3 retire far more, proportionately speaking and resulting in a better relative position. DAL and soon UAL with the new contract will allow basically direct entry CAs. How’s that compare to a 2018 junior CA? Alaska has the most senior upgrade at the major airlines, except Southwest.
You’re disregarding real, measurable, quantifiable variables for choosing an airline over touchy feely things like culture and perceived fleet awesomeness.
Money alone isn’t going to solve this.
