I had reservations for trips, but did not actually ticket.
$29 roundtrip, Atlanta to Fort Lauderdale, FL...on Delta.
$117 roundtrip(including taxes) Atlanta to Vancouver, BC on Canadian Airlines.
The best deals for international travel I have seen have been with couriers. U.S. to far East/Europe/S. America was $200 and under. I do not recommend courier travel unless you can go alone, have flexible travel plans, and can stay at least 1 week.
