I have a friend at Delta thats been there 2.5 years and decided to take widebody FO instead of upgrade.... hes doing good trips to Europe and home more than he would be as a CA, its awesome upgrade is so quick with so much movement, but when ur at the majors you don't need to upgrade at first chance because FO pay is still pretty sweet... with young kids QOL is what matters most. Wish they would call me... oh well
