We flew Delta from London to Atlanta and on the Orlando last year.
The long Haul was OK, IFE was OK, seats are not overly large or comfy, but we had a blanket and pillow each.
I always feel like we are hearded cattle when flying anyway so for the cost it was fine, they encouraged us to drink lots of fluid so refreshments were plentiful, food was fine.
The internal flight from Atlanta had no IFE, however it took off on time, landed early and was a super quick flight , both ways the internal flight was so quick, I thought it was excellent and the change of flight was very straightforward.
Value for money was good.
