I realize this is a ridiculous question but I'm very curious.
My parents are seated in 18A and B on todays BA0218 nonstop 777-200ER DEN-LHR.
Their itinerary lists the class of service as World Traveller, and they didn't know enough about BA (or call me to ask) to book in Traveller Plus. But the BA seatmaps for the 777 show the World Traveller section on the 772 starting approx row 26 and the WTP cabin starting approx row 21.
I realize that row 18 is within the margin of error for being in WTP, but I can't imagine it being in only WT.
Can anyone clarify?
