Summer vacation flight is on your mind?
My suggestion, book directly through the airline in case of hiccups.
I had booked a round trip flight for me and my son in November 2019 (EWR to Rome via Copenhagen) for Spring Break 2020.
Covid came and of course what would have been a wonderful getaway did not happen.
Flight was on Scandinavian Airlines but it was booked via Expedia.
It took me almost a year of efforts to get reimbursed.
