Funnily enough I came to this forum to ask this question.
There is something going on. I don't mind flying any day from June till a year later. Have checked 100+ dates and not a single biz seat on any day. Have even checked for March-April next year, 330 days out when seats are released and nothing!!
SQ is normally quite decent at opening reward seats and there were plenty of seats available on this route just two months back. I almost booked one for travel in Feb around 10 days before I wanted to travel. Checking in Jan there seemed to enough availability.
Even last year I came across seats quite easily when I booked a reward in Oct. This year nada.... zilch????
What's going on? SQ seems to release seats on every other route but this one. Are they moving in a 77W? Is that why reward biz seats are blocked?
