2.5 years. I got 737 Captain, so I'll skip the 777. I think 777 guys get the most days off, but I'm not sure what junior guys are getting. Some of the reserve guys do one trip per month. I didn't like the 777 destinations and the 16 hour legs. Plus, I wouldn't be the FO, I'd be an IRO and never "fly" the plane. I'd have to go to Houston every 90 days to the sim and requalify. I'd rather fly, so the 737 it is.
