Hi! Flystein is not yet another meta-search like Kayak or some travel agency.<p>It is human expert powered service which helps you to save on flights.<p>Flystein experts use hundreds sites, professional tools and special saving strategies(article just mention only few of them) and are interested only to save as much as possible and make clients happy, so happy clients would recommend Flystein to friends or blog about it ;) For BeatMyPrice trip requests the small fee is paid only when you get real savings, in opposite case the card authorization is promptly removed.<p>The service works best for any flights which cost more than lets say 500$ total.<p>For a simple trip just use your favorite metasearch like Kayak first and then submit results to Flystein as Price to Beat. If Flystein experts cant find you the real savings - your request would be completely free and you will be sure you got the best price already.<p>For more complex trips - go with Build A Trip and save tons of time and money.
