It wouldn't necessarily surprise me if it were 5 weeks.

I had no formal training in my role at CX (except for DG - 5days and load control - 10 days where I had to attend courses in HKG) - using the computer system for reservations etc was all taught on the job by trial, error and advise. This is all well and good as my customers are on the phone, and I have 5 other people here to help me out. At an airport (especially a small one) you don't have that luxury. If I make a mistake in cargo reservations, my GHA might notice it or worse comes to worse something is left off the plane. In an airport role you could stuff up their connection, compute fares incorrectly, mis enter information etc that would have worse consequences. My friend works for VS at MAN and she told me the other day US Airways sent someone there who was meant to go to Manchester NH... she had checked in with passport as ID so seemingly didn't realise until her flight was "taking a little longer than normal". That being said, I have no margin for error when completing load control, but as I mentioned that was a 10 day course with a 100% needed to pass.

Another point is i'm not sure about Skywest, but most airline computer systems aren't exactly state of the art. I still use a green screen UNISYS system at work that is text based, and requires me to memorise a lot of keystrokes and commands. That took weeks and pages of my own notes to remember. You seem a pretty switched on guy, but without GUI systems it can take a very long time to be trained!

Good luck... let us know how it goes
