We are flying from ORD to JRO via AMS and have a 5 plus hour layover at Amsterdam. I was wondering if there was a way to buy any sort of a lounge pass which will give us access to the KLM lounge at Amsterdam airport. We don't have any status with Delta or KLM but both of us have the Delta Gold card which gives a one day pass at a discount ($25 instead of $50/person) but can't buy one at a discount online, either. I was wondering if we could use the Delta Sky club one day pass to use the KLM lounge?

Can someone tell us what our options are, if any? Can we access any other airlines' lounge? We have club passes from AA and US Air which I think are pretty useless for this trip.

I will appreciate the help. Thanks.
