After looking for our flight on the internet and not finding it I called Delta to check on our flights. Well wouldn't you know it they decided to change our our plane from a 737 to Delta Express which is about half the size of the 737. They right away offered a refund I said no due to the fact that we got our flights fairly cheap. Well to make a long story short we are leaveing earlier in the morning on a larger jet. Some how I donot think that this will be our last change, but I hope that it is. They are blameing it on the war. I would advise anyone who flies with Delta to keep checking on there flights
