It turns out that it's a myth that the day before Thanksgiving is the busiest travel day of the year; summer weekends win that distinction. AAA's Troy Green told NPR, "There are about five to 10 days during the summer that are busier than Thanksgiving." Nor are there significantly more flight delays around Thanksgiving than any other time of the year. But this holiday definitely earns a spot in the top ten. It's high-traffic enough to be one of the holidays that some airlines add a surcharge for.
