Were those round trip or one way prices? If it's round trip, I might even think about heading over there this year...

Those *are* round-trip, and yes some of them are pretty amazing. However, those were just fares they e-mailed Jan 9th probably for travel between Jan 13th and 20th or something -- and only if you'll accept separate middle seats and are willing to change planes in Fargo, stuff like that. Not any use if you actually want to plan in advance, and very volatile, but a possible great deal for discretionary travel when you're sitting on the fence. If they are busier come May/June, you probably won't see last-minute "E-fares" fares like that, but you never know.

For grins I just plugged in my May 30-June18 dates for a ticket to Amsterdam and lowest fares came back at ~$1,000 from Seattle and ~$700 from Newark. It seems like it's always a crap shoot -- whether to wait in hopes of a lower fare (essentially hoping that the airlines are underbooked and get desperate)
