Glitch fares. Error fares. Mistake fares. They go by many names, but what are they exactly? Well, it's exactly what it sounds like, glitches and errors due to human or technical error that ultimately benefits the heck out of travelers, who are able to book flights for a fraction of the cost of normal airfare (like that one time I caught a glitch fare to Abu Dhabi for $187, roundtrip). Some of you reading this may have actually snagged the most recent glitch fare from the U.S. to parts of Africa, the Middle East, and Thailand. Congrats my friends! Hope...
