- 757-200 (non-Song)
- 767-300 Domestic
- 767-300ER International (economy class)
I do know that the 767-400ER, 777-200ER, and the international 767-300ER in BusinessElite (except the four reconfigured aircraft) currently use Rockwell-Collins IFE. I also know that the ex-Song 757s and the newly-reconfigured 767-300ERs with BusinessElite use Panasonic IFE. Does anyone with Delta know the rest of the fleet?
