I HAVE flown Ryan before, but YEARS ago.

I'm flying SXF/BTS/SXF for a 1 nite trip. I will be OK going to BTS, but, I'm a shopaholic, and I really don't know what I might buy while I'm there. I will TRY to get it all into a carry-on, but, I'm a little concerned about this "90 cabin bag" allowance on each flight, before forcing people to check bags. I know it's free, but, I don't want to be forced to check my important personal stuff. How do they manage this at the gate? Does somebody stand there with some sort of a counter?

It says that, if you pay for priority boarding, you'll never be forced to check your carry-ons, but I can't find a way to add it onto an existing booking, plus I really only want it on the return flight.

Also, how is boarding done? After priority, is it first come - first served? Zones?

Please advise.

Thanx!
