Fares frequently change so this post will likely be outdated by 11/11/16

We’re entering an era where we’ve seen unprecedented and consistently-offered low fares on international flights.  With a little planning, you can typically fly to Europe for under $600, Asia for under $700, and South America for under $600.  While you can typically find these fares on budget carriers (WOW, Norwegian, etc.), they’re also available on the legacy carriers (Delta, United, and American) which offer frequent flier miles and free beverages (on international flights).  I used Google Flights to find the flights listed below.  I recommend that you use a travel website (Orbitz, etc.) to book flights so you collect points from those sites as well.

Three sub-$500 options are listed below (some require a 5-night stay for the cheapest price).  Even if your city is not listed below, it may still have sub-$600 fares.1.  Barcelona, Spain  ($478)
