For what its worth fellas here is how we do it at Nutjets. We have to be in the blocks by 13:30 so you have 30 minutes to put the plane to bed by 14:00 and get to the hotel. No reasonable but company policy. If we are running late sometimes we can get the company to extend the time a little. Our FOM allows us to go over 14 for weather, pax delays etc and the FAA signed off on it. Hopefully no one does go over 14 but there are always some.
