Second place was a little closer — the cost of airfare (20 percent), gas (18 percent), and weddings (16 percent), were almost nearly tied up. Commuters filling up at the pump still couldn't get over the crazy gas prices this year, while many consumers struggled with airline fees for just about everything while traveling, from checking bags, food on board, head phones — you name it. Still, some of you were most taken aback by the high cost of weddings. Shelling out a truckload of cash for the plane tickets, gift, new dress. Whoa! It all adds up pretty fast, huh?
