I decided to take a trip to Vancouver, British Columbia to visit a friend who was living there this summer. I starting looking for flights about a month before heading out and was having a hard time finding anything under $600. My friend told me about Momondo and I was able to book my ticket on the same flight that was listed as $620 on other websites for $414!!!!
I also just bought a flight to Copenhagen during the holidays for $500, couldn't have done it without Momondo!!
