I will be flying on SQ12 from SIN-NRT-LAX next summer, although I haven't booked it yet. Singapore Airlines currently has a very good deal for this flight- around $1000USD one way! On the SQ home page, there is an advertisement which says "All in Fares at Exceptional Value." Since the price is so good, I am assuming it is part of the advertised sale? If so, how long will it last for? On Expedia I used the 'seat preview' feature, and from what they show the flight is almost fully booked in economy already. Is this seat map reliable? I would really like to know because I want to snag a seat on the upper deck in economy. I find it hard to believe considering its still 9 months away. I hope somebody can answer my questions, thanks in advance!
