Today, I was browsing for fares to Amsterdam using Kayak. I like Kayak as I can see every airlines price, and I can choose the airlines that suit me. When I was being directed to the: Luthansa site, Travel Merry popped up at just about $200 less for the same flights. I never heard of them. I then opened Lufthansa's site and there is no such fare. This should be a warning. I am retired, but I worked in the travel industry for 40 years. Only airlines set prices, and travel agents cannot charge less. After reading the reviews on here, this is a way for them to get your credit card info and then charge the actual price. If one is not is buying the tickets directly form an airline or a trusted travel agent, I say buyer beware. Ifthe price is low, that should be a red flag.
