I have a plane with a lease due to expire 08-Jul-51.
It is currently Su 01-Jul-1951, week 26, 17:00
Lease cost 2 240 USD / month
In the terminate lease window, it says "You may terminate the leasing contract of the aircraft at any time before it ends.
Early termination of the contract will cost you 50% of the remaining lease period's cost."
Do you wish to terminate the lease contract? Cost: 6 790 USD
The prices don't tally up. If it's 50% of the monthly cost, it should be 1,120. If it's 50% of the remaining lease period (1 week) then it should be 280. The terminate lease cost is over 3 months of lease cost.
