Have you ever successfully booked cheap airline tickets? What services for buying airline tickets have you used?

 

For cheap airline tickets, the best way is to book airline tickets with a travel agent. A good travel agent can get you the cheapest ticket than any online site. I also sometimes use spirit-airlines, which I recently found out about at https://spirit-airlines.pissedconsumer.com/review.html . The best time to book a plane ticket is three to one month before departure.
