Malev is a great airline if you like hungarian food and Tokai wine. Service is also excellent. If you want to fly direct to Hungary, there is no other choice out of JFK. However, the seats are slightly more narrow than US carriers in Business Class. I believe the seats have footrests, but they are older style BC seats. BC is rarely full on these flights.
Until the Austrian airlines partnership went south, I always liked taking Austrian to Budapest via Vienna.
Let me know if there is any info I missed here that you are looking for.
