I use that site all the time. Many flights from ATL-LAS and ATL-PHX are either 757 or 767 on Delta and only the 767-400 has the personal TV screens in them. I do everything I can to grab a flight on the 767-400
Seat E and F in row 7 on the 767-400 do have an ABSURD amount of leg room. I don't need it because I don't have much leg, but if you're a tall guy, grab those seats if you can. You can almost put another seat between row 6 and 7 in those two seats
