752 sunday or 319?
Welcome to the forum
Is this the flight you are referring to: flightaware.com/live/flight/USA1 … /TNCM/KCLT
It appears that there may have been a problem with the original flight and a 319 was substituted for the 757.
It’s always a good idea to try to put in the flight number URL in your postings for others to access easily. Just copy the URL from the address bar and paste it in the posting.
