I'm on a mailing list, darn, I can't remember who it is from, but this guy says to wait until the end of March, beginning of April for June airfares to drop.

If I can find who it is, I'll pass along the site and you can decide for yourself.

I am also flying to Europe in June and I was recently checking the number of seats on particular flights, and very few coach seats were bought.
