I have reserved two exit row seats,12 A and 12 C, on this aircraft for a 4 hour flight. This aircraft has 30 rows of seats with 11 and 12 being the exit rows. My question is whether anyone knows if the armrests can be lifted on these seats? I saw a video someone posted and it looked like these seats were in the video with the armrests up? The tray table appeared to be in the back of the seats of row 11, so no need to have it in the armrests. If the armrests do lift, I will switch my seat to 12 B to open up the window seat for someone else. Thanks for the help.
