Come fall, Halifax will no longer have a direct connection to Washington DC. United is scrapping the route.

This will leave HFX with just five daily direct round the year connections to the US, if the info on the airport's website is correct & complete: Boston, Chicago, Detroit, NY (JFK & EWR) and Philadelphia. (But I'm not sure that this info is up to date.)

During winter, there are direct connections to a few Florida airports listed, and for Saturdays during summer the airport's website also knows of a direct connection to Atlanta (which I can't find in the Delta timetable. ITA Matrix s.

Would anyone here know the background of this Delta flight during summer? It seems a bit odd to me. Are they flying tourists to Nova Scotia?
