I understand that the 9/11 passenger drop is hard coded and therefore not immune to oversupply warnings, but it gets old, every game, wasting hours messing with oversupply warnings and having to load limit routes. I would like to request that 9/11 is treated like any other random event and have the system turn off oversupply warnings for 6 months, starting September 01 and ending March 02. Hard coded or not, 9/11 was a random event and should be treated as such.
This is one of the parts of this game that make it an onerous job rather than a nice pastime it's meant to be (and usually is). It forces you to spend quite a few hours just going through the routes and adjusting seats on them - if you don't do that within a day (or you can't due to other commitments) those routes will be closed, possibly costing you slots an definitely a lot of revenue. Fairly annoying situation if you ask me.
