Forgive me if this has already been discussed/mentioned, but due to the fact that Delta is extending the life of the B767-300ER’s, will they be upgrading the First Class/Delta-One Cabins? I am looking at booking flights to KEF, CPH and ARN in 2022 and this aircraft is used. From pic’s I have seen, the cabin on this aircraft doesn’t look much like a premium experience. Thanks!
