I booked BUD-CDG-ATL//ATL-LAX//LAX-ATL//ATL-AMS//AMS-LIS//LIS-CDG-BUD. Since I backtrack through ATL, I'm pretty sure my fare is BUD-LAX. My outbound is in the beginning of June, with the rest of the flights in 2021. I've tried changing the dates of the outbound on DL.com and through the app, but I don't seem to be one of the lucky ones as everything causes a re-price at higher fares. Given the persistence of the coronavirus situation, I'd like to push my outbound back a few months. Am I SOL as far as outbound changes go until there is a cancellation by either AF/DL, or is there something else I should be trying?
