There are going to be variables at work here. First, it depends on what time your flight is scheduled to depart at. If your flight leaves after 8:30am, then you should be able to check your bags and get boarding passes issued at Pop....as long as you are flying on a participating airline.
The RAC counter (where you will check your bags and get bp's), is located outside the entrance to Pop. It opens at 5am....you have to be completely finished with your baggage check and bp's in hand no less than 3 hrs prior to flight departure time...so, if you have an 8:30 flight, you should be able to make it, but you have to be out at the RAC counter when they open at 5am.
IF you aren't exactly sure as to where to go to find RAC, just ask any Pop CM...they can direct you.
