http://www.foxbusiness.com/personal-finance/2012/08/30/how-to-get-cheapest-price-on-airfare/ a few questions on the article: "Prices are at their lowest between 18 to 28 days prior to your trip... Domestic fares are lowest 21 days before departure" I havent found that to be true. In fact, I saw no difference in prices if I book 3 months ahead, or 1 week. "Overnight flights can be good bargains" sounds good. and you dont lose a whole day in flight. "Buying two one-way tickets from different airlines may be cheaper than a round-trip ticket" strange, I have never tried it; but will check it out. Anyone done that? So that's say Delta flying from NYC to Vegas, and then United back.
