"PHL Economy Lot: Anybody with recent experience care to update us?"

I was there yesterday and paid the flat rate of $9 for a three hour stay. The rate is $9 up to 24 hours. I do not recall if the rate changes for weekly or longer stays.

Allow an extra half hour (minimum) to forty five minutes to get to your flight if you park here. The bus is supposed to come every seven minutes. The bus stops at each of the shelters in the lot and at each airline terminal. It took about fifteen minutes to get to the first terminal (A) from the economy lot.

When getting back to your car, you have to catch the bus at the baggage claim area. Otherwise, you are going for a long ride through the remainder of the terminals and to baggage claim, before the bus goes back out to the lots.

On the plus side, the busses were clean and the drivers friendly.
