In theory you could use Tor (in the config file you can hardcode a list of exit nodes that you want to use). In practice you probably don't want to do this because: 1) If not everything is correctly SSL encrypted on the airline website the risks are much higher and 2) there's a good chance that the airline will block open proxy IPs.
