This post assumes that GoGo are doing a MITM simply to block YouTube in order to prevent their network from being congested. My assumptions would be that
1) GoGo are blocking youtube in favor of their in-flight paid media services not just for badwidth
2) GoGo's MITM attack has little to do with media content but rather more about being able to read all the communications of passengers for "national security" purposes.
If they are decrypting and logging your traffic (including passwords) and communications, then I assume their scheme can be defeated by a VPN. If you want to send intimate messages to your lover, or discuss a political protest while in flight, without some nosy GoGo employee reading it, then probably using OTR (like Cryptocat or pidgin/adium), PGP (like mailvelope, enigmail), and ZRTP (Redphone/Signal) are a pretty good idea.
