We have our ‘regular’ flight booked for 3/10 from EWR – MSY, CO816 – Class W. The flight is always late, at least when we fly it. We can get away earlier that day but the previous flight, CO516 at 3:20 PM, only shows Class H availability.

What we’d like to do is try to get a connection through IAH which is a regular ERW – MSY route but at a higher fare. The only better arrival time at MSY involves 2 flights EWR–IAH-MSY, CO51–CO1423 that are showing Y availability only.

Are we closed out of a free same day 3 hour before departure flight change because of the Fare class differential?
