Check-in experience left a LOT to be desired. I had tried to check in online but couldn't figure out how to navigate the required steps. So, we got to the airport in plenty of time to check in at the counter. But once there (and my friend and I were the ONLY people at the counter at that time) the counter agents--all four of them--seemed to have difficulty in getting us our boarding passes. AND, they charged us $25 apiece for doing it. We were not at all happy about this.
