Our Delta flight tickets are restricted which means if we change the dates or flight number we have to pay a $100 penalty per ticket. My wife just called to tell me that the news is reporting several airlines waiving the penalty fees.
I called Delta to see if we could entend our visit by 3 days without paying the penalty. We are going in June. The Delta rep said the waive fee expires on May 31st. They said they may extend that if the war is still going on.
If you want to extend your trip or move your dates, I suggest calling your airline to see if they are waiving fees.
