When I see a cheap flight, especially a glitch or error fare, I turn into an animal and pounce like it’s my dinner and I haven’t eaten in ages. Book now, figure it out later. Thanks to a rule by the Department of Transportation, you have 24 hours to cancel a flight with a full refund—so really, I have nothing to lose and everything to gain when an error fare comes up. That’s how I found myself with a flight out from Portland, Oregon to London, England returning from Istanbul, Turkey back to Portland, from mid-November to mid-December for under $500 USD. That was less than a flight home for the holidays. (In the words of my friend, Kenna, #bookthatish!)
