During the month of October, Singapore Airlines is offering its latest "Spontaneous Escapes" discounts, which can be booked until September 30th. The deals between New York and Singapore may be worth a look.
There is a direct link to the offer.
One of the thinner lists we have seen for premium-cabin travel and the options for business class awards are disappointing.
The Premium Economy deals may still be worth looking at for people in North America. You can get flights between New York and Frankfurt for 36,400 miles in premium economy with Singapore Airlines. Extra legroom and decent in-flight entertainment for a small premium over what most airlines charge in economy class is appealing for a daytime flight back to the US.
It's probably an ok deal to fly from JFK and Newark to Singapore in Premium Economy for 56.350 miles one way. It isn't something to write home about, but if you're looking to travel next month, it may be appealing.
