I do most of my domestic flying on Delta, which has in flight Wifi (via Gogo) available on most (if not all) of their aircraft. The quality is really hit or miss. I've had flights where the connection was good enough to download large files (debugging symbols from Microsoft) and have one way Skype sessions (me typing, the other person with audio/video). I've also had flights where I could barely check my email. I'm not sure if it's the route flown or the other passengers using the connection or what, but the highly variable quality is annoying.
