Burning up days off to commute every week on oversold airplanes to slum it in a crashpad like a poor college student in a dorm room, only to fly multiple legs per day with a grumpy old stews doesnt sound fun either. Yes, 18-21 days can be long, but 16 days is more average, along with 2 weeks in a row OFF to do whatever I want and not have to think about work until the next month.

Tough choice though.
