If you want to make a comparison on something that makes a real difference in your work life as a pilot, you should be comparing the type of people you have to work with. Idk about some of the airlines mentioned, but NJ hired some real wackos about 12-15 years ago that make your tour absolutely miserable. Not just in the cockpit but in public also.
Can’t say it enough that HR needs to be kept out of pilot interviews. They are totally clueless about what it takes to operate in this environment.
