The comfort level in F is horrid if the pax in front of you goes full recline. You can pretty much wiped your nose on their seatback. Forget about the person getting by you without you getting up. Hell, it's a bit of challenge getting out of a window seat even AFTER the aisle pax gets up if the person in front are full recline.

DL needs to add more space between seats or limit recline on these 76's in F.
