- "seats measure up to 18-inches wide in economy, the same standard configuration found on Airbus widebody aircraft"

- "To minimise cabin pressure effects on the body, the cabin maintains a 6,000-feet average altitude pressure, roughly equivalent to that of a mountain ski town. This is the same cabin pressure as the modern A350 widebody, and it helps to reduce physical fatigue, headaches and jet lag."

- "Modern next-generation LED lighting systems aboard the A321XLR gently transition through customised hues, mimicking natural sunrises and sunsets to help reset the body’s circadian rhythm. Temperature control is split into three actively controlled zones, and airlines can even opt for heated floor panels to give passengers an extra touch of cozy luxury. Last but not least, advanced acoustic technologies have been integrated through the aircraft’s frame to minimise engine noise, resulting in a 50% noise footprint reduction compared to previous-generation single-aisle aircraft."

In a typical single aisle airplane, sitting in coach, you're expected to use the restroom "in your cabin" which is at the rear. If you're sitting anywhere _except_ the rear, your access to the restroom will be blocked for a significant portion of shorter flights by food/bev carts.

By contrast, on a widebody, there are restrooms front and rear. If your access to one is blocked, you can go the other way, and you can _also_ use the front or rear to access the _other_ aisle. It's the difference between feeling totally confined versus freedom to move about (other than having to hassle any passengers between yourself and the aisle).

I admit, with limited cabin service in economy, on a longer flight, the blocked aisle isn't such an issue -- but on the typical 1.5-3h narrowbody flight, the food/bev service does seem to be a significant obstruction.

I'm someone who would happily pay up for a lie-flat more frequently if it was priced at 2-3x a regular ticket rather than 5x+. Airlines are slowly expanding premium cabins, and I'd be hopeful that narrowbodies like this permit further growth, but the demand seems to be increasing faster than the supply, so the prices are still crazy.

Air travel seems like this as most airlines and manufacturers seem to bend over backwards for their wealthy and high margin passengers and basically treat economy class as "fine I guess we'll throw the rest of you in the back"

Mobile games seem the apotheosis of this as a lot of games are really about finding whales and any enjoyment anyone else has is really an accidental side effect.

Return was on their A330, which was noticeable worse in every way EXCEPT it's 2-4-2 seatings, so we had a pair of outside seats to ourselves, where on the A321, it's 3-3, so you have a neighbor in the window seat.

I fail to see what's innovative about "we shoved business class seats into a narrow-body aircraft".

An A321 is still an A321.

Flying internationally in a single-aisle aircraft is under any circumstances torture no matter how you sugar coat it: "Come fly in our modern, innovative sardine can."

By the way BA did this years ago with their London City A318 which doesn't exist anymore because it was a failure that merely burned money.

At this point, the designers of narrow-body interiors should be actively shamed for how hostile they have made lavatory designs. In a world in which every major flying population is aging and more overweight, yet every generation of airplane lavatories is even narrower and less accessible for everyone.

Also, the business class staff are so nice, they make you feel like a million bucks.

To the back of the plane, all you poor people!

1) The windows are disappointing. This is, I think, due to the fatigue caused by large rectangular windows that previously caused a disaster but it begs for improvement. A way to make large windows or get rid of all the windows and use very high definition screens to imitate windows with live footage would be nicer

2) Noise is still a problem. I am sure they are trying hard, even the engines are designed around addressing the noise issue but it would be a huge improvement to have this solved. ANC maybe?

3) Automate the pilot out. This is I believe an area where plane makers are pioneers but we still got pilots, I would love to see flying with a plane becoming about the same as taking an elevator.

IMHO travel times are reasonable, the improvements in comfort, cost and practicality are due. Airports themselves too are due for an overhaul, it shouldn't be taking hours to get on a travel machine.
