Well to update you on my situation, this was my first DL flight and I had signed up for Alaska's program when I booked these flights. Upon writing an email to DL I was offered 7500 miles as compensation for no IFE on the outbound leg. The only trouble was I don't collect skymiles, I was crediting my flights to Alaska. And I am not a frequent flyer by any means. So 7500 miles in an otherwise dormant account had no value to me. Given though it was a take it or leave it situation, they agreed upon request to remove the actual miles flown from Alaska and repost them to DL instead, so now I have the flights plus the bonus miles in one account (approx 21k miles).
