By that definition United maintains hubs in Amarillo, Tampa and Hong Kong. Lots of airlines are no longer performing heavy maintenance at their hubs.

- saosebastiao 9y agoNone of those are hubs, they're spokes. There's two components that make an airport into a hub: 1) Transfer operations. This means flight schedules are almost invariably determined by the hub airport, because they time arrivals and departures to happen in waves, which minimize the amount of time that passengers have to wait for connections. This means that you'll have a lot of staff to handle the peak load of a transfer wave, while that staff might be relatively idle at other times. 2) Maintenance operations: this means doing routine maintenance during layover, as well as swapping out planes for intense maintenance. This is why your hub layover doesn't have a pre-determined terminal for your second leg flight...it can and regularly will change if a plane needs to be swapped out for maintenance. A spoke city will have neither transfer operations nor maintenance operations. A minihub might have transfer operations but not maintenance operations (I've explained these are only viable regionally in other comments). But a full hub will have both.
