I got hired as a customer service agent at Skywest literally as soon as I had my HS diploma(since the job was held for me until I graduated). Outstations seem to have random hours depending on flights, but at the hubs its pretty black and white, AM or PM. The PM shift, on the ramp especially, seems to be almost entirely college kids where I work. Its as much fun as it sounds. Most college kids want to work the weekend so they can focus on school during the week. That the LAST thing I want, school all week then work all weekend? Please. That's actually why I dropped out. "Just 2 more days of school then I get to work all night on the weekends while everyone parties, YAY!". Don't set yourself up for failure, college is a lot more flexible than you think. Want your weekend nights? Work mornings, take night classes. Want class in the morning? Work nights, take morning classes. Can't fit 3 classes in before/after work? Take 2 that day, you may be in school a little longer, but it is what you make of it. But you're only young and stupid once, imagine what being young and stupid is like with flight benefits. If you want to be a ramper, take the job, organize your schedule around it. I'd recommend part time tho for extra flexibility, just pick up when you can.
This fall I am going to be a fulltime student and take it seriously, I can go to school in the morning and work at night. Now that I'm 21, I know a lot more about myself, and I'll have a much better time in college because I'll appreciate everything for what it is, not take it for granted and watch it fly by like many of my friends did. And I still have my weekends, and my flight benefits. I don't want to encourage procrastination to a career focused individual, but...if you really want to travel, and maybe you're more concerned with living life than rushing into your career...just sayin'.
