As of 9/6, MSY will once again be an all mainline station for AA....at least that's the plan at this time.
The two AA Connection ERJ's which have been flying MSY-STL will be replaced by one daily MD-80. So we'll see one less flight overall, but more seats.
AA will then offer a total of 16 flights per day: 7 to DFW, 3 to ORD, 3 to MIA, 2 to STL, and 1 to LGA.
Look for the resumption of BOS nonstrop service once the cruise ships and conventions come back in the Fall.
