During the investor relations presentation, there was a lot of talk about the NYC operation reaching profitability in 2014. Then one of the analysts wondered how long it would take NYC to reach Atlanta levels of profitability, and suggested Atlanta was Delta's most profitable operation.

Anderson corrected the analyst that, no, ATL is not the airline's most profitable hub. So, my question is, based on what we know, which is? Any thoughts/guesses/rumors?

MSP
DTW
SLC

It's not the NYC operation, it's not CVG, nor ATL nor LAX. My bet is one either Minneapolis or Detroit, because SLC has so many more regionals. And, using that dame logic, I'd guess MSP again because there are a lot more 50 seaters at DTW.

But what do you think?
