There are 2 issues, and they are mutually exclusive.
1) XJT guys hate OO, the AIRLINE, because of how hard we got screwed over by the Utah mafia.
2) OO PILOTS have a reputation as pretentious and arrogant d-bags. Sorta like hipsters without beards. Not ALL of them, but enough to give the rest a bad name. This is recognized INDUSTRY-WIDE, not just by XJT guys.
The first issue and the second issue are often mistaken for each other. Every now and then, you have a guy who thinks the actions of his company somehow have ANYTHING to do with his own value. These guys say stupid things like “you hate us ‘cause you ain’t us”.
* it’s worth repeating.....there are plenty of good OO dudes.....but you usually end up being surprised they work there. Sorta like meeting a Southwest CA who taxies slow or something.
