Training center in CLT was on the chopping block. They announced the closure and wrongly thought the staff would be willing to go to DFW to continue work. Almost no one committed. They then realized it would worsen the staff shortages we already have.
CLT is dirt cheap to operate. There is zero non instructor staff. One security person at the front desk. Remember too PSA and Piedmont do all their training there.
Interest rates on AA debt are really low. Cost of new aircraft will rise because of inflation and supply pressures. Interest rates on future purchases will be hire. Increase in oil costs will be less significant due to new fleet of very efficient aircraft. Every time I fly the NEO I am amazed at such low fuel flows.
