I got an email from airfarewatchdog.com about a special sale American Airlines is offering from Seattle to Cancun from Sept - Dec - $544 round trip. airfarewatchdog.com announcement The last time I got an announcement like this about Cancun flights, it was last fall for US Airways and we were able to book our flight in January for only 30,000 mile points each for the round trip tickets (normally the flight costs 75,000 mile points each). The fare special was the same, $540ish round trip. We only had to pay about $150 total for the international taxes after cashing in the mile points. The catch was that we had to fly in and out on a Thursday to get that deal - other days of the week were 75,000 miles each. So, I just wanted to pass this along because it is worth checking to see if this is only for Seattle, or if American Airlines is offering discounts to Cancun from other cities. If you have miles saved up on AA, it could mean the same great deal we got with US Airways. The flight for us from Seattle to Cancun normally runs between $700-$800 each for round trip tickets.
We actually booked our entire trip through AA for Halloween. They were less than Expedia or Orbotz from our city and dates.
