From now until Turkey Day, expect to add another $5 to your airline ticket price total for every day you wait. On some routes ticket prices are already 20% higher than last year. Rick Seaney is the CEO of FareCompare and he says, "The reasons behind this are threefold: jet fuel prices are remaining stubbornly high even as gas prices go down; airlines have been cutting seat capacity over the last three or four years, with even more cuts in the last half of this year; plus, demand for seats is relatively good."
