Same flight, different question. BA operates the 787-8 on this route, but in this instance it looks they're going to use a new 787-10. So instead of 35 seats in J and 24 seats in PE; there will be 8 seats in F, 48 seats in J, and 35 seats in PE. My wife and I are currently booked in PE on an American code share ticket. I am One World Emerald and she is Ruby (through American). Any insights on how we might be able to leverage this equipment change to get ourselves upgraded into J?
