Cons: I reserved a car a month in advance from the Pittsburgh Airport. When I got there, I was told that the reservation was not made for the airport but from their corporate center, which was closed (at 4:30pm on Saturday!). They could only give me a same-class car for 3 times the price ($150 for 2 days, versus $45 for 2 days), because the US Open golf tournament was in town. I went to another company and got a slightly better rate, but ended up getting a car for $120. Very disappointing!
