Mesa , AZ– Just when you think it’s too stupid to go back in the air, Delta.com offers the pleasant surprise of online check-in and home-printed boarding passes. A billboard on the way to the hotel says, “Sweating for free?! Get paid to test deodorants!” A photocopied sign at the check-in desk congratulates Gregory Allen for being selected guest of the day. And rather than redo my network settings in our upgraded room, I surf happily on a wide open wireless network that’ s bleeding in through the window. This is the way to start the week.
