You may bang on the legacy airlines, but American Airlines has a good thing going here with Gogo. The outfit has just completed installation of in-flight WiFi on 150 of its MD-80 aircraft, and in order to give you a better idea of how to prepare, it's now launching an online widget that'll let you know if your bird will enable web surfing when you get on. The tool is completely web-based, so any PC or smartphone can access it; the only real knock is that it only informs you of a "yes" or "no" 24 hours prior to departure, so it's still impossible to book a flight 3 months out and know for certain if you'll be able to hop online. This is definitely something that should be adopted by the other airlines (pronto!), but we can't help but dream of the day when something like this is unnecessary due to in-flight internet becoming completely ubiquitous. Ah, the future -- how you tease us so. Demonstration vid is after the break.
