My family and I used Counterflight for our annual trip to Europe. My flight concierge was really knowledgable and friendly and provided me different cheap options to pick from. I booked my flight right then and got a super price on it (about 45% less than what I would have paid elsewhere). When I checked the price a few days after, it surprisingly went up by $70, so I am really glad that Counterflight could assist me to buy the best deal at the right time. Absolute must-have site for budget travellers!
