I have been planning on a round trip BOS-AMS for the past couple of years. Finally found someone who would like to travel with me. I am looking to travel in March, April or May 2011. There have always been 60,000 Mile economy award seats available over the past 2 years. I have consistently checked availability monthly.

I checked yesterday and today and even when I select the "Low" days on the calendar for both flight segments the lowest available award seats are 75K and 90K?

Now, I did notice over the past couple years that on occasion there would be no 60K seats available, then a month later I would check and there would be some availability. Is this a common trend or has Delta really increased their lowest available award to 75K? I really don't want to shell out 75K-90K miles for a single economy ticket. That's insane IMO!
