Really?! They do that?! Although I guess kind of selfish, that would be good, as the last time I had to sit next to strangers on a long haul was incredibly uncomfortable...

Well I contacted the travel agent my partner used, as I was a bit concerned that they might ask for the card we used for payment at check-in, and the flights were paid for by him.

The travel agent also said that for our booking, as we are on the same itinerary, if my partner doesn't check in, all the flights on the itinerary would be cancelled, including mine!?

So he split us into 2 separate itineraries, now when I login to the 'manage my booking' section on SG airlines, it just brings up my tickets, instead of before where it made me give information about the both of us to locate the tickets, and then would bring up both of our tickets.

Thanks for the help!
