In a codeshare situation, does one look for the "coded" upgrade fare class, or the "operating" upgrade fare class?
Well .... this is only going to apply in NW-KLM and DL-NW really. It is the marketing carrier I believe. As I noted, the only place that this could get tricky is with "K" on NW and DL. So ... an NW "K"
should not work on DL metal, but a DL "K" (in theory)
should work on NW metal. Again, I invite anyone with experience on the point to chime in. With respect to NW and KLM, it needs to be a YBM NW coded fare on KLM metal. Again, if someone has different experience, please chime in, but that is a literal read of the rules.
