Yep. I have done 7 legs, almost did 9 til we broke. I used to do 5 a day regularly.

Now three is taxing. I like my two with 5-7 hours of flying and done for 14-19. Honestly though, you do get used to it, but I dont personally want to go back to regional style flying. All that said, SWA is good work if you can get it. all the buddies I have there seem happy enough.
