Because culturally you guys can be easy to make fun of from time to time. Between the surfer bro, plastic bachelor party captains and flying around at the speed of smell all the time it’s easy to riff on you. Most of the prodding I hear/see is this type and it’s meant in good fun (unless captain slow makes someone miss a commute because you guys are taxiing at a turtle’s pace).
You also benefit from the dues of all the union airlines because your airline is forced to appease you enough that you don’t organize. Personally I don’t care, the way things are set up it’s just a reality of the industry. There are some bitter people that have a legit chip on their shoulder about it though.
