Where is a starbucks when you need it? I thought they had something that if you got a cup of coffee you could get 1/2 hour of wifi access for free (well, as free as it can be when the coffee costs $5), but i have yet to see starbucks or ANYONE with food at the airport offer wifi access with a purchase. maybe I just haven't looked hard enough.
the vast majority of the airports I have been in do NOT have free internet wifi access. most of them have this annoying open wifi access point that once you connect, all HTTP requests are sent to a page that prompts you to purchase wifi access for 6 or 9 or 12 dollars, depending on the airport. how lame. I've been to atlanta, cleveland, mineapolis (sp?), phoenix, houston, and las vegas. of all of those, las vegas was the only open access point that I can remember.
for a future business venture, I think I'll rent a locker in the airport for $5 a month or what ever it costs, and call up the cable company and have cable installed in my locker. then i'll put my own access point in there and sell access for 3$. actually I'll make the first 15min free (and track by mac address or something). then make a deal with all of the food people in the vicinity of my locker. that way people can add a 'wifi sandwich' to their meal and get access. you see, on cooporate travel I can charge food to the company card no problem, but i'm not so sure about internet access. such a solution should solve everyones problems.
