Thanks all. Had 50k MR and card expires in December (not renewing card). Needed 2 round trip on US for a total of $600 so I decided to apply the 50k which left me with a balance of $100. I figured it was worth it to get rid of the MR and to get the US PQM toward keeping gold status. Plus, I am pretty sure we will get upgraded to F (3.5 hour flight) on this flight. All in all not the best possible use of the MR but not that bad either.
