Use online check in before you to the airport! Day before would be best.

While you might be able to use the kiosk's, I have gotten there on a monday morning at 6 AM and they all said "closed". I was so glad to have that home printed boarding pass.

later in the morning and in the early evening can be very packed and all the cattle lines fill up. TSA apparently removes staff and closes lines during the day to make sure they always have a nice big line.

Ditto on the RCC opening time issue. Do they all open at 7 evern day
