If it got to the stage that those aircraft couldn't land because there were no free stands at BRS I would go home!!
Im sure it would be worked out that there was always at least two free stands available. The airport of course makes money from diverts etc so It wouldn't be clever buisness practice to fill up all of the stands. At the end of the day even if the aircraft aren't based here you can still have massive expansion MV mentioned EZY SXF but to a bigger extent look at Flybe.
