    Hi – I have never received a Mistake Fare alert! Do they happen very rarely or am I looking in the wrong place??

      Hi Barbara! Are you referring to Thrifty Traveler Premium? If you’re a subscriber, you’ll get any and all mistake fares, unadvertised flash sales, and international flight deals to your email. They are not posted to the site. Mistake fares are rare, but when they happen, you’ll get a Premium notification via email immediately!
