2 tips - go to the A concourse and walk over the sky bridge that is still inside security...some great views of planes from up there including most of the Frontier tails if you're into that sort of thing.

Also, you can use free wireless internet access from the Continental lounge on the A-concourse too. I tried just outside the doors of the club with no luck (near the elevators, top level), but when I went around to the area in between the tops of the escalators, I got a great signal. There's even an electrical outlet on that bridge IIRC.

P.S. Might want to check out the Red Carpet Club Meeting Calendar in the UA forum - might be someone there willing to let you in for free...
