I have accidentally terminated a leasing contract of one of my planes. It hasn't been delivered yet and is scheduled to be delivered on March 25, 2016. What will happen now? Will the plane still get delivered? will I get my money back?
Delivered = yes. You can use the aircraft for the period between date/time of delivery and date/time the lease contract ends. That should be maximum one week.
To equip the aircrafts with seats is IMHO no a good idea. Just "forget" that aircraft.
Money back = yes. Your deposit less one week leasing.
