If you're flying American Airlines out of the Quad City Airport to start your holiday journey, a computer glitch may have made your travel more complicated. CNBC says the glitch let too many pilots schedule time off around the holidays and, according to a memo CNBC saw from the airline to the pilots union, left many flights from American hubs like Chicago and Dallas without pilots right around the holidays.

American Airlines spokesperson Matt Miller told CNBC that the airline is working to solve the problem and expects "to avoid cancellations this holiday season." Since the Quad City Airport is served by Mesa Airlines, Envoy Air and Skywest Airlines under the American Eagle brand, flights in and out of the Quad Cities will probably be fine. It's what happens in Chicago and Dallas if you've got a connecting flight that could give you a Holiday Travel Headache.
