Since it only had a business Elite service, no first class at all, the seat were comparable to domestic business seat with United or American. The seat cushion were firm, uncomfortable, and did not lie flat, the slope was not comfortable and the width were tight. The Monitor was outdated and emitted poor quality video and audio entertainment.

When one pays a premium for business class, one expects something more than economy. The seats were very little better than economy, width was perhaps 1/2" wider, did not lay flat and not at all comfortable. Both my wife and I slept very little and could not find a comfortable position when we were attempting sleep.

CDG-ATL, business class. Seat was not worth the price we paid for it. Very old material, no way to lie down properly (the seat doesn't fully expand, stays as a slope). It was impossible to sleep in such a seat. Low quality entertainment system : small screen (on an arm in the center armrest), poor movie choice.

Shanghai-Narita, and Narita-LAX. Nowhere near flat and non intuitive controls, but acceptable for sleeping with a few adjustments. I found that adding some air in the lumbar bladder and putting the full size pillow behind my shoulders fit me pretty well at 5'9" and retracting the foot rest helped keep me in the right position. Get the middle section of seats so you and your neighbor have aisle access without crawling over each other- the 2 seats nearest the windows on both sides don't have enough clearance for the window seated passenger to get out if his neighbour is reclined.

These seats are the best that I have experienced with an American carrier. Astounding for a North American business class product really!

Amsterdam to Seattle, an old Northwest airplane and seats are not comfortable at all in the upright position - I felt that I was tipping forward all of the time - the seat seems to be split in the center (cross-wise). It's more comfortable in the recline position but it's not a lie flat seat by any means.

Delta's 767 seats Detroit DTW to Frankfurt FRA are the worst business class seats I have ever experienced. They don't lie flat, leg room is too short, the seats are too narrow, and there are lumps and seams in exactly the wrong places. Very frustrating when you pay for business class to be able to sleep and then you can't.

HNL-SEA redeye where the seats don't have a footrest and won't recline more than about 6 inches. No personal entertainment system for a 6 hour flight. They have a lot of nerve calling this first class and flying a plane like this.

New staggered business class seats, outbound chose a "D" seat next to the window, return I had the "D" seat on the aisle. I was not able to sleep in the seat next to the window due to lack of storage and the way in which the leg/foot rest extends into the "tunnel" in the bulkhead. On the return, my aisle seat was at row 10 and was comfortable, with more storage (particularly for blanket and pillow prior to needing them). Since the business class lavs are at the rear of the cabin, my sitting at row 10 was convenient. The seats have an excellent AVOD touch-screen system. While still on the narrow side, the new six-across seats are a vast improvement over the outdated and uncomfortable seats on the 767-300's.

The new business seats are very comfortable. However, if you are a big or tall person the bed can be very small to move around in. The only design flaw was the tray table - getting it out is easy, but putting it back into storage was a fight.

I am 5'8" and found the angle lie-flat seats very comfortable. The pop-up foot rest is a nice touch and I found it stopped forward sliding. I agree that the window seats seem to be a tad more comfortable.

Business Elite Seats on Delta's aging fleet of 767-300ER's can be best described in one word: punishing. The seat width is essentially the same as a seat in economy, and headset plug and controller cannot be located or accessed without standing up. ATL to MAN, and from DUB to ATL, and in both cases spent more than eight hours each flight wide awake, leaving each flight feeling as if I'd been crippled. Delta claims that it's installing new "flat" bed seats in its 767-300 fleet, but until or unless that happens, I can't in good conscience justify paying for business class on Delta when the options on other carriers to the UK are so much better. The AVOD system kept failing on the flight to Manchester, and the monitor (which is on a metal arm) kept falling down making watching anything at all impossible. The quilted blanket was nice and the pillow would have been great if it had been possible to get into a position where sleep was possible. The lavs were not maintained during the flights and were pretty gross toward the end of each flight.

How did Delta manage to get it so wrong with selecting this seat? The seat width is very poor, particularly in the full flat position where turning onto one's side is very restrictive. The seat structure is such that the seat cushions are very flat and form, and do not offer a comfortable sitting or relaxing level of comfort. There is a real lack of privacy - even in the full upright positions, the seat have a strange framework / pod style that means you have no real privacy, and when fully flat, well, there is nothing by way of privacy. The headrests are small and do not offer any proper adjustment either. Finally, what was Delta thinking of when installing such a pathetic IFE screen - this is supposed to be a product that will last, but already Delta has something which is not competitive with the better carriers across the world. It might be competitive with other US airlines, but not when one looks into Asia or the Middle East.

These old planes with very old seats from Northwest, at least 10-12 years old, are awful! I do not recommend these seats. They have no sense of privacy and do not become comfortable for sleep as they do not lie flat, and even the recline positions for reading and IFE are bad. Yeah, they're a step up from economy, but hardly worth the extra cost in miles or money.

A little narrow, and I felt it slanted downwards at the head a bit, but it is comfortable enough to sleep on, even for just an hour or two. The seat was very comfortable in recline mode to watch the AVOD or read. IFE screen is too small and it is a bit odd feeling on take off and landing with the angled seats. Don't sit in the rear section of the business cabin next to the toilet. The light from the loo will bother you. If you book 7A or 7D, there is a real sense of privacy.

The true lie flat is not 21" as advertised. Moulding and the entertainment unit reduces this to about 18.5". Very narrow and difficult to get comfortable for a 5'10" man.

These are tough seats. There is no storage room so all bags (even a computer bag) go overhead. There are no usable pockets so even a headphone case had to go in the briefcase and into the overhead. IFE is fine. Lie flat actually depends on your legs and feet entering a tapering cone that just simply doesn't work well. Padding is adequate and oversize pillows and a quilted blanket help. The seats are an obviously cheaper version of the pods that other airlines have done better.

The new lie flat seats are lousy for tall and/or larger individuals. The width of the seats very narrow unless you are thin. The lie flat is too short for me as I am 6'2". My feet were crushed into a tiny space under the seat in front of me and never allowed me to stretch out. The seat controls work fine, but that does not help the decided lack of space. The seats could have been made wider had the table that is built into the seat been made smaller. The seats are very hard, resulting in a sore behind after a few hours. Wide regular seats, such as those used on the 777, would have been a far better choice. All around a big disappointment.

It is nice to have a true lie flat seat, but it is a squeeze for larger men, particularly in the shoulder area when in the bed mode. This is less of a problem on the window seats than in the middle seats, and I would strongly recommend that anyone over 6 feet choose the window. The problem is made worse by the narrow triangular heat rests, but that is compensated for by the huge pillows that DL gives you on the overseas legs. The traveling companion isolation is real, but I found it better is you split the aisle between you versus the middle seats partition between you. If traveling alone, it is perfect. You can adjust the seat any way you want but it requires a lot of trial and error with the buttons, versus the older business class seats. The fact that you can't open the tray table if the seat is too reclined was annoying. I would definitely select this product over the standard BE on a 767, but I prefer the non-lie flat BE seat on the 777.

Seat was comfortable and well secluded - window seats in the odd-numbered rows appear to have slightly more space. All seats now have direct aisle access. Food and service were excellent. Only downside for sleeping is that the armrest doesn't descend when the seat is reclined, so slightly narrow around the shoulders. I'm 6' tall and had enough space in the flat bed to stretch out.
