So I booked a RT ticket back then for 80k, now when I check DL.com I see that the timings changed and I get the folowig message - There has been a change affecting your trip. If you are not satisfied with this updated itinerary, you may be eligible to change your flight(s) at no extra cost.
I believe I have to call DL to change it, would they change me to any date I request, or it has to be award space available?
