Need the advice of seasoned Delta travelers as I'm in what my daughter states "that's a you problem". Long story short booked a flight for Christmas day a long time ago with a great price. We decided we want to leave earlier and drive due to a family situation. I read Deltas "Contract of Carriage" and in the refund section I understand it to read a full refund will be issued same way the ticket was purchased if Delta changes the scheduled time more than 90 minutes from the original time of booking. When I purchased the tickets the flight was scheduled to leave 7:00am now it states 8:25am. I realize its a change of 85 minutes not 90 minutes so I'm asking if anyone has ever been in my situation and what was their end result. I want to call customer service but don't know how to go about it. What should I say or not say to get a full refund?.....help
