Hello,

First time poster. I am flying from OKC to CPH on January 28th for business. When I search for flights on delta.com (or Google Flights or Skyscanner), it doesn't find any results. And not only for the 28th but several days around it.

But when I look on Air France's and KLM's websites, there's a reasonable itinerary at a market-competitive price. Upon further investigation on Delta's website, the flight that AF and KL are using that Delta isn't is the CDG-CPH (AF) or AMS-CPH (KL) leg. Is Delta no longer doing code shares with AF and KL for some flights? Is this a weird bug?

I'd prefer to book with Delta for ease (and a better website, imo) but I need to book soon. What's going on here? Thanks for your help!
