Tip # 1
To get the best deal to buy any merchandise, you need to buy and compare prices. The same goes for plane tickets. If you want cheap airline tickets, compare the price between several different airlines. This task could be easily done using some of the famous travel websites such as Orbitz, Travelocity, Expedia, Cheap Ticket, CheapAir.com, Booking Buddy.
Sometimes you have to search different travel websites to get the best result. However, there are websites that search for 100 plus travel sites at once and find the cheapest prices. kayak.com is one of them. My favorite is itasoftware.com

Tip # 3
You can get a cheap plane ticket even cheaper by using an airline coupon, others may call them a voucher. Northwest Airlines distributes the zone voucher to the general public. I got them in an envelope with coupons for Val Pak. Continental Airlines provides a dollar voucher based on a return airline ticket. They recently teamed up with Chase Bank to lead the promotion. United Airlines compensates customers with vouchers of $ 50, $ 75 and $ 100.
People put these vouchers on eBay, sell.com, craigslist in exchange for good or money. Some of them have no monetary value (just like grocery coupons), and you pay for their time to collect and send vouchers.
