Bonus Award Miles (RDM) - 3x fare on Flights to HKG & SIN, 5x EWR-MEX
Just came across this whilst browsing the United website for offers form Europe back to the mainland:
Earn extra award miles on flights between the U.S. and Hong Kong through February 28, 2019 (registration required).
Unsure if it was discussed elsewhere but thought I'd post it up!
Safe Travels,
