My SQ suite review Jfk-Fra
Singapore 1st class is nice, but not really necessary, given that the business class bed is just as good.
Here are the advantages of 1st over business.
1. The added privacy, because of the door (the biz privacy is not bad)
2. Perks, like PJs and a Amenity kit.
3. Extra Attention
And really not much more.
The suite Super Saver award is 57K points (Very hard to get unless you book far in advance) 110k for the standard Saver and 430k for the standard. (If booked online, otherwise it's 15% more expensive
The Biz Super saver is 47K and the standard is 67K.
