Reply To: Seat Reservation on UK positioning flight when First on International flight

Have done that same routing a few times now and its your status or lack of it that controls the NCL to LHR seat selection. As noted this is probably down to BA IT quirks.
I think it’s a pretty good bet you’ll be seated together but CE (and the flight) is often full whenever I fly the NCL-LHR route.
Enjoy Chicago, it’s a great city to visit.
