These are some of the deals I’ve found for round-trip international travel in June, July, and August (some even extend into the fall, when the weather’s heating up Down Under). Dust off the passport (or apply for one) and get them bags packed:
Chicago to Dublin*, Ireland – $498 on Delta
Chicago to San Jose, Costa Rica – $277 on TACA
Los Angeles to Buenos Aires, Argentina – $598 on United
Los Angeles to Frankfurt*, Germany – $517 on Delta
Los Angeles to Manila, Philippines – $588 on Delta
Los Angeles to Panama City, Panama – $297 on American
Newark to Sydney, Australia – $712 on United ($573 from LA!!!!!!)
San Francisco to Tokyo, Japan – $454 on Air Canada (early-mid June only)
Washington to Frankfurt*, Germany – $526 on Lufthansa
*Once in Germany or Ireland, you can hop over to almost any other major European city for as little as $40 each way.
And right now, round trips from the East Coast out West and vice-versa are also stupid cheap, often $200 or less, so not living in San Fran or LA is no excuse; DC people, hit that Chinatown Bus to The City. I found these fares by first checking the forums on frequent traveler website FlyerTalk, then verifying on the individual airline sites, or on Farecast, Orbitz, Expedia, Farecompare, or Airfare Watchdog (which is especially handy by alerting you of fare sales from any airport you desire). If you can, play around with the dates or destinations; I’m sure you’ll find something worth salivating over.
