I found skiplagged.com showing affordable rates than regular kayak and priceline. You all might find it useful
but if you all know other sites that give better rates, please do share...
here's a news behind this website which is an old news....
United Airlines (UAL) and Orbitz (OWW) filed a civil lawsuit last month against 22-year-old Aktarer Zaman, who founded the website Skiplagged.com last year.
The site helps travelers find cheap flights by using a strategy called "hidden city" ticketing.
The idea is that you buy an airline ticket that has a layover at your actual destination. Say you want to fly from New York to San Francisco -- you actually book a flight from New York to Lake Tahoe with a layover in San Francisco and get off there, without bothering to take the last leg of the flight.
