Maybe the original writer wanted to know the destinations served. Here are the ones I know of, others may add to it or give specific routings, some are obvious, others aren't. BOS, JFK, CVG, ATL, MCO, DFW, SLC, SEA, PDX, SFO, LAX, SAN, PHX. It's that last one that I didn't know until recently. SAN-PHX apparently is a continuation of a flight from JFK. If I could just get an afternoon flight ATL-SLC or CVG-SLC with B/E, I would be happy.
