On one of United's B767-300 from EWR to TXL and I seem to remember the seats reclining slightly more several years ago. More specifically, it seemed like the in-seat TV screens we're almost bumping into your face when the passenger in front of you reclined. Now, there seems to be much more space in front (and much less recline for you).
Has United (and other airlines) been reducing the amount of recline for all the economy seating?
