DA been through it personally and whilst liquidators argued at every step of the way, eventually they gave up and just paid. Some of the contracts involved were very large and into the millions (not mine) but they were paid under court order. There was an argument as to reasonableness or excessive, but at the end of the day the contract prevailed in every case.
Would have thought pilots would have no difficulty arguing long periods as reasonable but get good advice.
Good luck to everyone.
