2. Yes, bidline as a bidding function has gone, but it has been replaced by a powerful new system which remains better than any other system I know of in any other airline.
How do you know? It's still being "built".
There are some issues with it and it has been delayed until at least September because no-one wants to take the risk of implementing it during the summer when the schedule as it is looks a bit optimistic.
It may be that it turns out to be the best thing since sliced bread but until everyone is bidding with it simultaneously, any suggestion that it is "better than any other system" is conjecture.
