Does the delta 747-400 have tv channels in economy?
I have flown on 2 delta airplanes that have ptvs and they had channels (such as espn) that i could watch but i was wondering if my flight to honolulu would have them also in economy class?

Check Seat Guru for the aircraft type and seat amenaties. Check Delta for aircraft types and make sure that they operate the aircraft in question on your flight.

The "Delta" 747's are really northwest 747's that have been repainted follow the merger of the two companies. If NW did not have them equipped before, it is doubtful that Delta will retrofit them now.

Seatguru says yes, though by the sound of it they are bulky systems, which means they are older systems. I'd take a good book and an iPod.
