I thought D7 is leasing in all their birds ?
That should by and large insulate them from so called life cycle risks no ?
They have some under finance leases and some under operating leases. Some aircraft also come directly from lessors, AerCap.
Lower acquisition costs also mean lower finance costs as interest on a lower purchase price will be lower. However, engine maintenance costs should be quite close whether it is on the 787 or A339 - I think that they are using PBTH agreements for engines.
We won't have too long to wait before we will know... Farnborough Air Show is only four months away...
