We were flying out of Pittsburgh for our Bahamas trip. Since we live 3-4 hours away it was required that we had to find somewhere to put our car unless we planned on shipping it overseas. We parked in Extended parking which was relatively easy to find with signs giving directions. It was $8 a day max, so in total $40 for the duration of 5 days we stayed parked. Not too bad compared to what we could have paid elsewhere. It is a long haul if you're walking into the airport but a free shuttle is constantly awaiting picking up the new arrivals parking at the airport. Got to us relatively quickly since my body was still not out of the car when it pulled up.
The ride to the airport was easy and pain free. There were spots to throw your luggage but enough room in the seats to toss it next to you since you almost have the whole shuttle to yourself...almost.
It was painless getting to our airline aisle, and everyone was helpful with questions. The girl that took care of us to get our plane tickets was extra extra cheery and just made the process so much less stressful.
The process of going through security checkpoint was fast but the one we went to with a no wait line was somewhere across the airport so we had to take the train shuttle to get there, and get back.
The airport was full of a huge selection of stores and restaurants so even with a 3 hour wait for boarding, you have plenty to do.
Otherwise the airport wasn't too packed so it was easy to get around without running into people with our carry on bags. One of the better airports I've been through.
