I am booked in business class TG 677 a B777-300ER. (it's the 17:30 afternoon commuter flight) I am trying to book a seat that is next to the window with the armrest/shelf on the aisle.
My problem is that my booking airline has a different seat position than Thai airways. If I was booking through TG I would take 12 A or 15A and with AC 11A 14A
TG has the following diagram (same as seat guru)
Thai Airways
Air Canada which I booked through has this configuration
Apologies if this has been addressed elsewhere but I didn't find in search and I am completely flustered. Who should I rely on?
