Opinion and personal preferences are useless. I'm sure to a domestic rj pilot, the lifestyle of a widebody FO seems quite appealing. For me, today 737 CA is best for my situation. I don't have a lot of day off requirements, and I can front load my b fund with time and principal. As my kids get older, the bes seniority and days off of a widebody FO will have more appeal. So what?
As far SLI goes, the same applies. One seat in and of itself is not better than any other, except to the point that the individual pilot decides what is important. It's not about your actual seat, it's about the number of choices of seat you have to choose from based on your seniority. I've read a lot about the career expectations at UAL of being able to hold widebody Captain for x number of years before retirement, but no one has mentioned that the same expectations existed at CAL. The junior wb Captain at CAL is 20% seniority; the junior wb Captain at UAL is 15% seniority. So even with fewer wb aircraft, there was greater opportunity on the CAL side. ***I only included 777, 747, and 787 in those calculations and left out the 767. I am on the CAL side, and I will admit that is a bit misleading to say that we have wb Captains at 60% (2005 hire date), even though it is technically true.***
