Here's an idea for US.
They operate out of many airports with multiple gates. Here in BUF they operate 5, and I know other upstate cities they have many gates as well. Besides the early morning rush and evening stayovers US really does not need all the gate space that they have. I know they have always had a large presence here, but perhaps they could cut some corners by cutting down the number of gates which the airline operates out of individual airports. I know CO did this as part of their restructuring plan and now any non-hub or focus city will not operate more than 2 gates for CO unless it is deemed "profitable" or worthwhile. So ultimately my question would be, do you think if US cut down on overhead such as large numbers of gate leases at airports where they were not necessary this could in turn help them on their way to recovery.
