"air cards" are pretty much a thing of the past any more. Most laptops don't even have a slot for them. Most people will just use their data plan off their cell phone and connect that way. One thing that I did when we were having some work done on the house, was I went to the local library and used their internet. The library was in a large city and had some "private cubicles," so I made sure I got their early enough to make sure to get one. No one even ever bothered me or my computer, so if someone has access to a library card, you could go that route or even get a guest library card if it is in a larger city. Places like Starbucks or McDonald's or any place like that would be too "iffy" in terms of privacy, etc.
