Also, for your return trip, ask about upgrades in the KLM lounge if you have not upgraded in advance as they sell decent last minute upgrade offers there (but only ex-AMS).

This is going back almost 4 years, but I was able to upgrade AMS-ATL to World Business Class for 289 Euros (at the time, about $375.00); the offer was made through the check-in kiosk in one of the KLM Crown Lounges in AMS. Totally worth it.
