Did you check whether this is a leg of a long-haul flight?
Sometimes these flights are a utilization of resources, as aircrafts are currently not profitable on other routes. So if you check the contriubution margins widebodies used short-haul at least are CM II positiv.
Buy 787 or A330 not lease, and aircraft will be profitable on short routes
Problem is in game system who prefer leasing instead of buying aircraft's
This is only because it includes depreciation only. If you concider capital costs the calculation looks diffrent. The decision will depend on your growth strategy and the free cash.
It's basically what I have said before. Disregarding aircraft related resoruce costs short-haul widebody flight's can be positive.
I think it has been mentioned in another thread, that they are addressing that internally, but that it still needs balancing.
As you can take from the board, there's a lot going on right now, so they might need awhile to answer and they certainly can't answer to all threads on the board, though they do try. Kindly be patient.
