I have enjoyed First Class on both DL and NW - had the opportunity to fly first class on the overnight flight back from Hawaii on NW - HNL to MSP - the amount of room was significantly better than the DL flight - and this was one of the best night's sleep I have ever had on a plane. We didn't leave Hawaii until something like 9 p.m. so a large meal was the least of my worries - I was hoping to fall asleep ASAP since I would be losing several hours - and the amount of space on the NW plane was wonderful.
