My apologies if this has already been discussed - I tried searching for (what I thought were) key words in this thread, but didn't come up with any hits.

Has anyone had any luck using EF (in some way) to search for "all gateway cities" at once? As in, searching for all possible US gateways from London on AA (i.e. searching JFK, PHL, CLT, RDU, ORD, LAX, DFW) all at once?
