I am trying to do an ITA search for nonstop flights or connections where the long leg is on either a widebody or narrowbodies with premium service. I'm looking to go from PHL to LAS, but JFK is an option.

For AA, my preferred airline, they have the following: AA Flight 726 PHL-LAX often operates with a widebody, and connects to LAS. They also have what they call an A321T with premium service flying JFK-LAS. I don't know about other airlines. At the moment I'm 10 times as interested in AA as in other airlines.

For the PHL-LAX trip, right now I can do a search on AA flight 726 with the qualifier aircraft t:787 and find out what days it is operating (it's usually an all-or-nothing thing by month) and then search PHL-LAX with AA:726 AA as the routing, and I'll get the fares. For JFK, I know which flight numbers are the A321T but I don't know how to search for multiple alternative flight numbers, like AA100 or AA200 or AA300 then AA+. AA operates many JFK-LAX flights with other routings. I'd prefer to be able to do a single search with different flight numbers than a separate search on each originating flight number.
