I'll enlarge on the Big 3 widebody discussion. I don't believe any of the Big 3 have more than 20% of their flying in WB seats. And, it seems more and more of their international flying is being outsource to their codeshare partners, so that number is only going to go down.
Also, the WB left seats at the Big 3 go extremely senior. If you were hired on the leading edge of the current hiring binge and you were in your 20's, you might have a shot at more than 10 years flying WB left seat at a Big 3 company.
Contrast all of that with Fedex. Over 80% of our flying is in WB seats. And with so many folks hired directly into the MD, 76, and 77 there are literally hundreds of folks here who will spend their entire career in a Fedex WB seat. A large percentage of our WB flying isn't international flying, but you'll still get paid WB pay. And, anyone hired in the last 5 years, hopefully, should be able to get into a WB left seat within 5-7 years, and remain in a WB left seat for the remainder of a 20+ year career.
Everyone always concentrates on which airline has the highest pay, but they forget that there are only a select few at the Big 3 who will ever get to see that high pay rate for any length of time. I suggest you think about the long-term career earnings impact of all of the Fedex WB flying available before you jump ship.
