US has already annouced that they will be adding three new nonstops from MSY to CLT and PHL come September. Now, browsing through the schedules today, I noticed that US will be making the following upgrades:
1) One of the MSY-DCA E170 flights will be upgraded to an A319. Not a surprise, seeing how the 170's are usually overbooked by 9 or more on a daily basis.
2) One of the MSY-PHL flights (inbound into MSY from CLT) will be upgraded from an A319 to an A321.
Also, the US ticket counter here and all three of their gates are getting ready to receive a massive facelift, including new signage and carpeting. Work should begin this month.
