Had to change flights due to COVID for two different people from two different cities to get us on the same international flights with connections, sent my preferences in an email to *******@cheapair.com as they request when you call and I got a call back maybe an hour later confirming any changes in flight prices and verifying my new flight info. Very friendly, efficient, I honestly put it off because I assumed it would be a nightmare, glad it wasn't at all difficult or stressful!
