Also I think auto bidding is happening I just can't prove it. There is fast and then there is somehow being the fastest on every turn or two day that comes up. It tapers off as the month progresses because said pilot probably has much fewer holes in his schedule to fill.
No it's not illegal per the contract but it's certainly not ethical. At XJT we had a guy who submitted up to 800 requests the second opentime opened. It was crashing the system. He was found out and told to stop but otherwise had no consequences because there was nothing in writing to say he was wrong. Back channels eventually exposed his name and he finally quit for another regional.
I love first come first serve more than any other system especially after lines are awarded by seniority and IOT is by seniority. I lose plenty of trips to junior guys but it's the only shot they have and one day stagnation will happen and junior guys need a way to improve their schedule. That said, the opening needs to be later in the day and auto bidding should not be tolerated. If you're doing it and you think there's nothing wrong with that then your moral compass needs some adjustment.
