Delta is bad form my experiences and I will never fly them again...
find out how much time the flight needs to change by in order to change for free and watch closely..
I had huge issues they cancelled my flight put me on an earlier flight which would not work because of a cruise and would not change... I had to call the corporate office in Atlanta it took hours......
at this time our tickets were grandfathered form the bag fees... being out flight was cancelled it looked as if we purchased the tickets after the cut off date.. (
DCL collected the fee for Delta with express CO found out the night before) Delta told me they can see this but we nneded to pay go on line and e-mail them all the information to get a refund......
thankfully I kept ALL of the paperworks and showed DCL at checkout and they let me go without paying
GOOD LUCK..
I would leave it as is and suck it up otherwise expect problems and headaches that will be far worse
I will never use them again and it is sad as the were years ago one of the best....
