I am not sure if you are aware of it, but there has been a long-standing ethical debate on whether it is okay to borrow you back in a plane. In that debate, Delta looks to have taken a page when they announced that they would limit the amount of their seats and hope to reduce "passenger disputes", according to a travel expert.
The travel expert is Scott Mayerowitz, who runs Travel Guy's Points Guy where he reports that it starts this Saturday, Delta's fleet of the Airbus A320 aircraft will reduce the seat support in coaches from four. inch to two, and in first class from five and a half inches to three and a half.
Attending takes pain to point out that this is not an attempt to make more money by hugging multiple seats on the plane. As Ekrem Dimbiloglu, Delta's product and customer experience director said Mayerowitz,
"We don't add a single seat to the plane … It's not really a gateway to reduce your legroom. It's not the purpose here. For seats, or anything else, the cynics would be right, but this is really about more personal space. "
It is worth noting that seat-lingual-related conflicts are a real problem, so much so that there are actual products available to let people disable lying on the seat in front of them.
In fact, the airline's Passenger Experience Association (APEX) went as far as making an infographic about seated retracted etiquette:
I have to say I think it's good with this. I almost never put on my seat because I just don't, well, feel I'm worth it. Why should I steal some space from the person behind me, move their seat screen at a strange angle, or turn into their laptop? What am I, a sultan? It's just not worth it, and it has never been right with me.
Delta says that the change on A320s is a kind of test, and in anticipation of customer reaction and feedback, they decide whether to expand or not change the change to their entire domestic fleet. International flights are not scheduled to be affected.
