Slick In-Flight Wi-fi Move

Fun fact: you can pause your time with in-flight wifi. This means you can buy just an hour and spread it out. Check email quickly a bunch of times during flight, and pause the service while you compose replies, etc., etc. Of course, if you want to spend the entire flight merrily surfing, you'll still need to pay for full-flight wi-fi.

To pause, just return to the web page where you paid for the service. Somewhere on there (you may need to read a FAQ) is a control to pause service.
