I still would like to see that the lease extension more than 1 year before the end of the contract wouldn't rise the lease amount (and that the price is not going up, but down in case an extension of 1 year or more, because the aircraft got older)...
but
the first thing I'd love to see is, to select the lease length in 2 combos instead of 1.... 1 for the years and a second for the months (or weeks) ... that would make the system way more flexible and allow us to select length's like 3 years and 4 months
