Sorry if this question has been asked. I am new to the world of using miles to upgrade (as I know have the miles to do so) . Not to sure how early/late to do this and do have a few questions below, so thanks for the help


I am flying EWR-HKG on CO . The fare class is B.

I would like to use my NWA points to upgrade the flight from Y to C.

#1 How many miles do I need to do so? 12,500 or 25,000

#2 How do I go about upgrading, do I call CO or NWA?

#3 How long will it take to know if I can upgrade the ticket?

#4 Does CO or NWA issue me a new ticket if it has been done, will requesting an upgrade cause a problem to my ticket?

#5 Most importantly, am I able to earn any miles if I upgrade the ticket?

Thanks for the help

You'll need to call NWA to initiate the upgrade since its with WP miles. I think it will be 25K since its a B and not a full Y. Not sure about how long to see. NW and CO were and I think still are linked but with the divorce date coming things might be tight. Also, CO has gotten pretty stingy with upgrades so its a bit iffy there.

Bit off topic, but since pmaddock has answered your question:

if it's clear, look out the window! I had the most incredible views of the North Pole from that flight, and couldn't believe that I was the only one on the plane looking out. (Others couldn't believe that one $%^$#%$# had his shade open, but hey...)
