Merry Christmas everyone. Just bought a ticket BCN-LHR-JFK roundtrip via the Finnair website but BA metal. The European sectors in economy, and the transatlantics in premium economy i.e. WTP. AY codeshares all the way. When I try to select seats on the BA website, I'm seeing the economy seatmap for the transatlantic sectors, rather than the WTP cabins. Oh, and the Finnair website isn't giving me any seat selection option at all! Any theories/workarounds beyond calling Finnair or BA after Xmas?
