Are there any other FF programs (accessible via credit card spend) that have generous stopover rules? The reason I like SQ is because they allow you to purchase up to 4 stopovers on saver awards at $100 each, even on one-ways, and even on star alliance awards on other Partner airlines.

American doesn't allow stopovers, Alaska only allows a stopover at hub cities and with only one other airline at a time, United requires more miles than SQ and is an inferior product. I hear ANA and JAL allow multiple stopovers, but points for either aren't as accessible as SQ which transfers from all 4 major flexible credit card currencies.

I also forgot to mention that I have about 55k British avios as my disposal for short intra-Asia flights on OneWorld metal, if necessary (but I'm looking to save them and top them off for one way J tickets BOS-DUB to start my European trip later in 2017 aka Honeymoon #2, or two RT tickets to Hawaii)
