KLM Special Fares to Europe
You have until the end of tomorrow to take advantage of some great deals on flights to Europe, including Eastern Europe. KLM, the Dutch carrier, is offering return fares as low as $929 including tax from Toronto or Montreal to a number of European destinations. The reference is https://packandgo.klm.com, then check plan and book, and special offers.
Travel must start between May 7 and June 18, or between September 11 and October 15, and it includes a free stopover in Amsterdam. The list of places you can go for $929 return is large, including Moscow, Copenhagen, Istanbul, Bucharest and Lanarca. Fares are somewhat higher, but similar deals are being offered from KLMs other Canadian gateways.
If you are planning to travel during those periods anyway and can commit to specific dates this far in advance, you won't find much lower fares. Unfortunately the tickets are not refundable and change fees are large, $300.
