Do not try to save time by paying for the Terminal Return at PHX. Allegedly, you pay $35 and a driver drives you and your luggage, in your car, to your terminal thus bypassing the wait for the shuttle and longer walk. We waited 15 minutes for a driver, had to go to customer service where a guy drove us over to Gold customer service and THEY had to find us a driver. Thirty--five minutes later we got to the terminal. Ten minutes after the shuttle. It's a ripoff and the staff - except for our eventual driver - was indifferent.
