Automated Call Back Service

I just tried to call Southwest Airlines for some information, but all the customer service reps were busy. They now give you an option to enter your phone number and receive a call back when it’s your turn in the queue. They say you don’t lose “your place” in the order of calls, and you don’t have to wait on the phone. They tell you approximately how many minutes it will take until you receive a call back. My range was between 13 and 21 minutes. Now… we’ll see if they call back.

UPDATE: They called back 15 minutes later. Nice.
