I am considering a business class ticket on BMI that is a code share which actually goes on United. I am sure we all know possible reasons why one might do this, so I won't go into more detail!

My question is how to find out what fare class it will map into on UA. The BMI fare class is JNC1S.

Also, this fare only seems to show up using online ticketing companies (like Expedia, etc.), not on the BMI site itself. Is this common, or will I not be allowed to book when I finally get to the last step?

If it's for real, will I be able to go on the UA website and select seats, etc?

Thanks for your help. This is a new area for me!
