Icelandair is offering some great fare deals to several European destinations this fall, but you’ve got to book them while you’re still thinking more about sunscreen than scarves. The best prices available as I’m writing this is $608 round-trip from New York to Stockholm, Copenhagen or Oslo, and $618 round-trip from Boston to Frankfurt, but there are plenty of great fares on this sale – although the prices are bound to fluctuate, so the sooner you can grab the deal that suits you, the better.

Some of the other sample fares are:

• New York, Minneapolis or Boston-Reykjavik – $694
• Boston-London – $696
• Boston-Amsterdam – $689
• New York-Paris – $700
• Boston-Paris – $702
• New York-Glasgow – $830
• Minneapolis-Amsterdam – $860

The prices quoted don’t include some fees and taxes, and there are a few other cities from which you can take advantage of these sale prices. The departure dates vary by your departure city, but it’s roughly a September-October departure window. Be sure to read the deal details to find out for sure when you’d have to leave. You’ll have to book your tickets by June 30, however, and that’s coming up quickly – so don’t delay.
