Am I right in understanding that if the FB booking engine shows availability of multiple seats in La Premiere that’s reliable? I am seeing 3 seats (!) on the flight I am interested in. I am after 2 of them, but would need to top up my balance from Amex MR points to complete. I’d like to make sure I am not missing anything before I do the points transfer (e.g. that the engine may show availability but when completing the booking it limits to 1 seat). Any input is appreciated!
