Contracts will come and go at least three times in the hypothetical pilot’s career. Delta and United will always be at the top. Pick the airline that fits your personality the best/has the pilot domiciles you could see yourself living in and flies the aircraft you’ve always wanted to fly to the destinations you’d enjoy spending time in. The current hiring/opportunity for pilots is nothing short of “once in a lifetime “ and it won’t last for much longer (3-5 years max). Get the interviews and go with your gut and don’t look back.
