Sami is right, in the real world it's a case of "use them or loose them" just like in the game
I can say without doubt that I work for an airline that does not utilize all of it's slots at LGA and we are not at risk of losing them.
If that was the case when ATA went out of buisiness the FAA should have taken possesion of there slots and sold to the higest bidder.
As I recall ATA's assets were sold in court to all the various airlines that wanted them it up to the Airline to use them in the USA. I cannot speak for Europe or the World
Sorry real life is not use them or lose them in the USA
Well that is the USA - I (and I believe around 6billion others) do not live in the USA! I live in Europe where slot controlled airports confiscate under utilised slots which when considered is a very good idea. Why should airlines hold slots, particulartly at highly congested airports, that they don't or cannot use? In this case the game (and Europe) has it right. If we didnt loose the unused slots people would abuse it and take all the slots regardless of whether or not they can use them, just to prevent the growth of the competition.
And for the case of ATA I cant comment specifically, but if the slots are owned by the airline and they go bust, then I believe the administrator of the bankruptcy can sell the slots to the highest bidder just like any other asset to pay creditors and I believe this to be the case in Europe too.
Ok. Then what about putting slot-trading on the list?
Slot trading would be a great addition to the game
