Charter flights for future Drupalcons?

I'm curious if it would make economical sense next time to run charter flights out of major cities for future Drupalcons. I think we could negotiate better prices with the carriers, and it would be like an extended Drupalcon party.

For Drupalcon Paris, a New York to Paris charter would have been great. Maybe for Drupalcon San Francisco, a London-to-SF charter would be practical.
