KLM Codeshare Credit
 

I took a flight on a KLM-coded aer lingus flight...didn't even know it was Aer Lingus until i boarded....now NW is denying me credit....as i read the policy on KLM codeshare credit it's ambiguous....anyone experienced anything like this....??

Sorry! http://www.flyertalk.com/forum/frown.gif Not lately, no, but I fear that you are out of luck!

I had something roughly similar with EW flights that were KLM coded. I got credit for those for 3 years, and then all were denied following the switch to the new NW system this past summer.

I argued, without luck, that the NW web site section for KLM is the only one that does not specifically state that flights need to be KLM operated, as it does for all other airline partners. I was told by my NW contact then that the omission was not intentional and that WP should perhaps change it. This discussion happened in the Fall, and today I see all is the same as for the description. Based on the wording on the NW site, your claim is reasonably strong imo.

Where/when did you book the flight? If it was done in the US they are required to notify you of the presence of a codeshare on your itinerary and the operating partner. If they did not, then you have a beef with KLM or NW or whoever was the booking agent. If this was done in the US, you should consider a complaint to the FAA with cc's to your favorite airline... Even though this may not solve the problem, the psychological satisfaction would be endless.

Otherwise a simple letter to KLM in Europe might get you a few miles thrown your way. I presume this was, in any case, a short AMS-Ireland flight?
