As part of its 25th anniversary, American Airlines is giving a special offer a day for 25 days. Most of these offers are pretty weak. However, there’s one solid deal: 25% off award travel within the US, to Hawaii or to the Caribbean & Mexico. Book by May 31st and travel August 22-November 8. That means most Caribbean travel is only 18,750 miles, while a free flight to Hawaii in coach is just 26,250 miles. Hurry, because the capacity controlled awards will go quickly (especially to Hawaii).
