I leased an airplane different than the rest of my fleet. Is there a way to terminate the lease (and take a loss)?
Yes there is, If you go to the aircraft tab and then to "my aircraft" and select the desired aircraft you will see a page with all of its' stats and on the top right there will be a terminate lease icon. The loss you will take will be 50% of the remaining lease amount, so if it is on a long lease it will be a large amount, if it is a 3 year lease it will not hurt too much.
