http://finance.yahoo.com/news/trick-cheaper-flights-hiding-plain-022700026.html Want a quick 30% discount on your family's trip to Europe or Hawaii? In the crazy airfare world, sometimes buying two tickets is cheaper than one. Pairing two discounted tickets together to create your own connecting itinerary can often be less expensive than flying on one ticket, if you take advantage of airlines' city-specific specials, or create your own route using discount airlines. The strategy comes with serious trade-offs. You may have to recheck bags or stay overnight in a connecting city. And if you're late for your connecting flight, your trip could be canceled as a no-show. But mileage junkies who take advantage of ticketing quirks have been using this strategy for years. For travelers dealing with some of the highest fares in years to Europe, Asia, Hawaii and other long-haul destinations, doing it right can save hundreds of dollars a ticket.
