One other thing I forgot is the Qantas shuttle. QF runs an A330 back and forth from lax to JFK once a day. It is equipped as an international flight with the angled lie-flat seats in j.

This is my favorite way to fly lax-JFK.

Due to our laws here (foreign carriers can't operate domestic service), you can only fly on this flight as part of an international itinerary. So, you cannot just turn up and buy a one way JFK-lax. BUT - if you add it to another itinerary that includes international travel - even if that other travel is a few weeks later, you can book this flight. I once flew JFK-lax on QF, stopped for two days in lax, then flew lax-lhr on AA - but because it was all in the same record, I was able to do the domestic leg on QF metal. Qf's fares are pretty reasonable because they don't usually fully fill the shuttle flight. They only have one a day, so you give up some flexibility, but if you're leaving on a Friday night from JFK to lax, it probably fits your schedule. The QF flight leaves JFK from the BA terminal (t7), and you can use the BA f lounge (but not the ccr ) at JFK.

You will also get BA tier points for this flight.
