Even at the height of TWA's operations, they never had more than 4 nonstops a day in the market, plus a few one-stops. I highly doubt 5 MD
-80's a day! Maybe one or two for connecting purposes.
Smells like a typo to me.
The extra section to MSY
is great news however, a slow but sure build up of STL
might be in the cards. All those empty gates...better to build it back up a tad than risk a major LCC assault, tho no one seems too interested at the moment.
