Pilot on the rise: You're oversimplifying. You can't compare apples to oranges, the question is "how many credit hours" does a pilot get, not "what is the pay rate per hour".
If everyone only flew 83 hours and got 83 hours of credit, your analysis makes sense, but different airlines do it differently. I know that check airmen at Jet Blue can easily get 120 credit hours per month, UAL pilots used to get credit for lots of stuff that wasn't hard flying, and Fedex pilots really don't fly too much compared to passenger airlines, so they get pay credit and rigs.
From the folks I know that do it, it's possible to make more than $300k at Fedex (it's also possible at SWA according to rumor I don't know anyone that does it there), it's certainly reasonable to make $225k at SWA as a captain and at UAL now, the captain pay is now around the $130k to $150k, same as Jet Blue.
Also SWA has that weird trips for pay system that I get bored hearing the explanation to, so I don't know much about it. As far as I can tell, it's a cross between houly pay and mileage pay and too complicated for me to care too much about.
Oh, and Falcon guy, night freight sucks. Day freight sucks. You're on the freight ramp using porta-potties when the passenger guys are drinking Starbucks and picking up a copy of Maxim.
The lifestyles are totally different. Flying freight means sitting around a lot, frieght ramps, K-loaders and other un-romantic stuff. Yes, you get to see International stuff, but one of the most pathetic sights I've seen was in Paris at an art museum.
Three Fedex guys were wandering through the museum, "chatting" with each other about the art. They were stiff and uncomfortable and stuck together to see the sights, just like they had probably just been stuck together for ten hours flying across the Atlantic. If that's the romantic life of an international pilot (hanging out with your crew of uptight guys who complain about the cost of admission to a museum) then you probably made the right choice.
