It’s a nickname Isom likes, he told me last month at Skift Global Forum, because he believes D0 — that’s airline speak for flights that leave on time — is the most important metric for operations.

New York–JFK – The tenth-largest hub for American in terms of number of flights, the ninth-largest in number of destinations and American's secondary East Coast hub for international flights. About 7 million passengers fly through JFK on American every year, or about 19,000 people per day. American has about 12% of the market share at JFK, making it the third-largest carrier at the airport behind Delta and JetBlue. Since 2017, American has been reducing its international operations at JFK, opting to expand its Philadelphia hub instead. JFK also serves as a major connecting point for other Oneworld carriers.
