No more DL JFK/BUD, much to our chagrin.
Sure, fly AF and buy cheap zed (zed low). Probably on Hop! I've been several times when we flew. It was one of Boss' fave routes. Our second fave just below PRG. When are you going there?
You can likely zed from any major EU city. Check matrix.itasoftware for options, then check $ on DLnet.
