sounds like it would sometimes be worth it to pad your group to make it a group with a couple non flyers if you were shy one or two to qualify
Call the airline group booking desk and be prepared to do some hard negotiating!I arranged a group booking while in YOEC for 100 guys to go from LAX-JFK some 8 years ago and knocked down the asking price from $375 to $175 plus got some free tickets thrown in as well.
