Good luck. This info will not be easy to acquire. Labor would love to know the percentage of profit on every departure, as would every competitor. Do some research on the united feeders and the bidding process they had to endure during the beginning of the united bk. I believe the average 50 seater was competing for around $3000 a departure. Don't quote me on that number, but the process was held by a "third party" consultant and several numbers were thrown out in the public on purpose so each different feeder could underbid the other.
