Travel Websites--such as Priceline, Orbitz, Expedia and Travelocity--present the broadest range of airline ticket options, allowing almost infinite options in date, route, airport and airline company. They can offer good deals, especially when the purchase is bundled with hotel stays, rental cars or vacation packages; visitors should always also check with the indicated airline for comparable deals before purchasing from other Websites, though.
The traditional method of calling the airline to buy a ticket allows personal interaction with a human being, yet that may cost extra. A cheaper alternative is to explore an airline's Website, which often guarantees the lowest ticket prices. In addition, members of the airline's frequent flyer program--such as OnePass on Continental--can offset the cost with mileage points.
A travel agent has access to reservations systems unavailable to the average consumer. She can thus untangle complicated routes or book obscure airlines to exotic destinations. Her agency may also buy tickets in bulk at wholesale prices, offering big discounts to the consumer.
