I have flown out of Allentown.It's really easy to get around. They have a long term parking lot that has a shuttle that picks you up by your car. I don't remember the cost but checkout their website for prices. They also have a short term and another lot that may be called long term. Maybe the one with the shuttle is called the economy lot,it is just as you come into the airport on the right side. The other lots are a little farther in .If you make a mistake and miss the economy lot you can just drive out of the airport and come around in a circle.You don't have to go back on the highway. I hope I am not confusing you.They might have a map on their website. I hope this helps ypu. Have a great time! Paula
