The popularity of threads on flying in the US reminds me of what I find to be one of the biggest inconveniences there - how to connect to the Internet.
My own solution is to sign up with SBC Yahoo! dial up
http://www.all-free-isp.com/sbc_yahoo.php which you can join and then cancel within one month at no charge. You have to give a US street address, which can be your hotel or FBO. When I go to cancel, I tell them exactly why, and they are always completely charming about it.
However, there must be a better way. SBC local numbers are only available in larger towns and cities and for instance there isn't one at Las Vegas, NM. (That's New Mexico, not Nevada!).
So can anyone please suggest a better method, preferably using a toll free number?
