CHARLOTTE, N.C. --  Hundreds of travelers from all over were once again stranded in Charlotte overnight as an American Airlines regional carrier suffered a technical glitch Sunday night.

• Glitches have impacted 70 flights at Charlotte Douglas airport. 
• American Airlines says technical issues led to a backlog of flights Sunday.
• Check your flights before heading to the airport.

The airline is operating on a reduced schedule after being forced to cancel all of its flights Sunday night.

American Airlines officials say about 70 PSA Airlines flights were canceled Sunday because of another technical glitch.

All American Airlines flights operated by its regional carrier PSA Airlines will be canceled after 7 p.m. Monday.

This comes just three days after another glitch canceled more than 600 flights on Thursday and Friday.

American Airlines told Spectrum News they are doing everything in their power to get things back on track. American has some of its IT engineers from its Dallas-Fort Worth headquarters in Dayton, Ohio helping to get the issue resolved at PSA headquarters.

They also said they will be reaching out to every customer affected.

Charlotte is the largest regional carrier hub airport in the world.

The airline encourages passengers with flights Monday to continue to check their flight’s status before coming to the airport.

Charlotte Douglas International Airport released a statement Monday regarding PSA flights:

“Charlotte Douglas International Airport continues to provide assistance to the airlines and our passengers as PSA and American Airlines work to resolve their operational issues. We are not sure when these airline issues will be resolved and we strongly recommend that American Airlines passengers with tickets check their flight status before coming to the airport. This issue appears to be isolated to PSA flights. Passengers on other carriers are not affected by this issue.

The airport remains in an irregular operations plan, which was activated Thursday to assist stranded passengers and we remain in that operational status. This includes extended concession and checkpoint hours, additional aviation department support staff and making available emergency supplies to travelers including diapers, wipes and formula, blankets and pillows. We are also assisting in coordinating ground support with additional busses to bring passengers back to the terminal, as necessary. We remain in constant communications with American Airlines and PSA as they continue to work to resume normal operations.”
