My UR will never be used for AF.
(unless there's a discount)
Has chase ever offered one?
Yes
Now on par with Singapore to transfer from all programs to one airline.
Please explain why you wouldn't. Is 50k miles with Delta, no fuel charges to TLV and 50k to South America.
I don't know the whole parsha of flying blue. I don't have amex and only dealt with UA miles.
They have the same 12.5k OW to Hawaii as KE and are easier to deal with and ime have more flexible stopover options
Regardless of their great uses, you're still better off using amex or citi for them
