The list of cities losing DCA service effective in April 2014 is out:

Since NewAA pledged to maintain flights to small/mid-sized airports in the USA, foreign destinations like YUL & NAS and large airports like DTW & MSP had to go. (Perhaps not coincidentally, this gives DL a monopoly on the latter two non-stops.) Nine of the airports are small cities in coastal NC/SC/GA/FL.

Discontinuing these 17 cities accounts for 60 of the 104 slot pairs to be given up, with the remainder to come from cutting frequencies to remaining destinations.

Bids from other airlines for these slots have been received and are being evaluated by the feds.
