ghilis - the problem with Joey is he's NEVER done the other flying. Seven years in the business, recently hired at Spirit, never flown long haul, never flown w/b's, never flown long haul international trips. All of this with a background of having flown 3 a/c professionally(not counting GA). Cute.
I get that guys like doing X, year after year. Turns. Or Europe, or Deep South, or trans-cons. Others switch. Having the option is nice.
Reasons guys do the long haul flying - more pay, less B.S., more time off, interesting layovers, bigger cockpits, quieter cockpits. And it's different flying. Not hugely different but enough differences to make it interesting. All items that Joey has limited exposure to or never experienced.
