Going on ET513 from JFK-ADD in mid-Dec, and oh did my heart skip a bit when I saw a 789 (ET-AYD) make an appearance on yesterday's flight on this route. Have been starting to track the distribution of 788 between the lie-flat and angled-flat, but this was a surprise! I assume it was a one-time thing with ETs schedule, but still, one can dream...
