Hello All , I hope this finds everyone well. I spent 2 hours on the phone with Delta today. We were supposed to be flying to Alaska for a cruise in May. Delta just changed their policy to use your credits was expanded till 2 yrs. Maybe Southwest will follow suit. We booked for November. The rep told me she had been booking flights all day for November. I know one thing the flights were definately more expensive. At least I didnt have to spend any $$ today and had credits left over.
