Flight passenger asks who controls entertainment center for extra seat, ignites etiquette debate

Some planes may have more than the usual amount of legroom - giving passengers an entire seat space of room due to placement near the exit door.

"Seat 29F on a 757 has no seat in front of it. It's just 28D and 28E because of the exit door," the person wrote. "The seat is great for extra legroom on flights where I'm not getting upgraded."

Fox News Digital reached out to both the Reddit user and Delta Air Lines for comment.

A photo shared with the post showed the fellow passenger looking at both monitors with her bag underneath the seat in front of the poster.

Reddit users took to the comments section to share thoughts and tips as well. 

Another agreed, adding, "It's your space."

"That looks like your monitor, honestly. They have one already," commented a user.

One said, "That space is supposed to be yours. End of story."

"That is your space. Ask them to move it. I am the most nonconfrontational person I know, and I have asked many people to do this," suggested one user.

"When the FA [flight attendant] asks you to stow it, you can point to the bag that's under the seat in front of you," added the user. 

California-based etiquette expert Rosalinda Randall told Fox News Digital, "It would seem logical to use the screen and space underneath the seat in front of you."

She shared that the Reddit user could call the flight attendant to settle the issue or "forget about it and store your belongings in the [overhead] bin."

"In a non-accusatory manner, [the person could] say something like, 'It's a bit confusing, but that is my designated space.' Or, 'Are these yours? Sorry, but it looks like I'm going to need my space,'" Randall added. 

"Safety and civility should always be our approach and main concern," said Randall.

Randall added, "In today's easily sparked society, giving up a small space underneath a seat may be the better decision."
