what I tried to do is look up a one-way trip from Jacksonville, Florida (JAX) to
Geneva Switzerland (GVA), leaving on 06/23/2017.

I know the following flights are available and can find searching separate segments but can't duplicate the flights searching on Delta Site for
JAX -> GVA, departing on 06/23/2017.

The flights I'm looking for are
Delta 2033, Delta 70, Delta 9616 (Operated by KLM)
JAX-> ATL ATL-> AMS AMS -> GVA

If anyone has the time, would ask if you could search the Delta site for a
one way flight from JAX -> GVA (departing on 06/23/2017) and see if you can get the above 3 flights to show up as being available.

Thanks
