Bailing out indicates helping the major airports. Nothing is further from the truth - the 'major' airports will work to their capacity attracting all the extra business they can handle. Oxford, Southend, Biggin Hill etc are fighting as hard as they can to get the extra, leftover business; the scraps in reality (and there will be plenty of scraps to go round).
If anything it will be the ANSP who 'bails' out these 'minor' aerdromes by providing the service to the aircraft that the airports can't...
