AA and DL offer nonstops to all three of those cities from JFK, as does UA from EWR. Do you have a preference between those two airports?
In what class of service do you expect to travel domestically? Internationally? How much do you expect to spend on airfare in 2022? (AA is going to a "Loyalty Points" scheme for attaining status, so how much you spend will matter.)
You can compare each carrier's nonstop destinations from NYC by Googling "JFK airport wiki" and "EWR airport wiki" and then clicking on "Airlines and Destinations."
Each of the three airlines also has airline partners for earning and redeeming miles.
