Possibly the worst airport I've flown into. Flying in I already had a car reserved but it took over an hour to get into a car and out of the airport. First you go to the car rental counter in the terminal and wait to get the contract set up. The car rentals are managed from a different building and it took 20 minutes for a bus to show up to take us from the terminal to the rental facility. When the bus arrived it was standing room only. On arrival at the car rental facility it's a fairly long walk from there to the individual pick up locations though the parking garage. No walkways just stripes to walk between. Then you wait again for a rental attendant to look over your contract and point you in the direction of the type of car you've reserved. After that debacle I determined to allow myself an extra hour to return the car and be on time for my flight. Return was somewhat better although the stop designated for my airline turned out to be incorrect because of construction. Returning the car only took half an hour from driving into the garage to arriving at the terminal. That meant I had plenty of time to make my flight so I set up my computer for the "free" WiFi. For free you're required to sign in again every 15 minutes. You can upgrade your service for $5 for an hour or $8 for the day. But you probably won't need more than an hour because you won't have found a place to plug in your computer or other rechargeable internet ready device. I ended up sitting on the floor next to the luggage carts because there was an outlet there. There was one other outlet I saw on the concourse but two people were already plugged in there and that was the limit. Before 9/11 tightened security and the major computer age I used to fly in and out of BWI fairly often. It was an attractive airport and close to home. Since then I've mostly used one of the two DC airports but I got a really great deal on a flight to BWI. I don't know whether in the future I'll consider any deal good enough to get me back into this airport.
