I got this card with the primary goal of flying SFO-JFK ps on UA.
I decided to do some more research on how I could make it work for other trips and haven't found too many other good uses given my location in SFO. If you can think of a good one, do let me know.
YQ make it very hard to use for travel to europe as US air has left *A.
The option to redeem on LOT seems difficult as I need to find positioning flights to ORD, toronto or JFK. And then possibly another to the destination in Europe.
I prefer to use BA avios on Alaska for hawaii, cabo and puerto vallarta. But if UA has availability then then M&M could be useful.
Carribean is 35k and would involve connecting in IAH. This could be interesting.
Another interesting route could be to Central america. Avianca flies SFO-SAL and then I could connect to another destination from there.
