Well I'd stick DXB
at the top of the list, but if you want to look at other REALLY big hubs in terms of total movements, and couple that with which airlines made the most profit, then
you have to include PEK
I wouldn't stick any european hub there because european carriers have sustained heavy losses over the last few years, and even US carriers have largely outperformed them. Traditionally you probably could point to LHR
, but things haven't been smooth sailing in europe recently.
If you measured it a completely different way, rather than total $$$ profit over all, you might find some of the smaller carriers like Finnair come out better than expected.
I'd say we should start with somebody getting the top 10 IATA carriers in terms of overall profit, and then looking at the hubs relative to each airlines profit. Some carriers, like Emirates, it will be very straight forward. But Lufthansa for example will be harder as FRA
operations are split. And LAN... I expect they are doing well but with all the different LAN's around the place that one is going to be hard to pick which is its most profitable..it might even be GRU
(through TAM!) ..
