When I call AA to book, they are very unhelpful. What should I do?“Sherry, this is a great example of why you should become an expert AA.com user. American Airlines has very few partners that fly to Jamaica unless you want to route through South America, so all of that award availability should be visible on AA.com. If you plan it correctly, you can also get great use out of those 100,000 miles. Here are the mileage requirements for one-way award travel to Jamaica:MileSAAver Off Peak — 12,500 milesMileSAAver — 17,500 milesAAnytime Level 1 — 27,500 milesAAnytime Level 2 — 37,500 milesMore importantly, you should know that it’s incredibly easy to keep your miles active. You can extend the date of expiration with any qualifying transaction like a single dining transaction or a purchase through the AAdvantage E-Shopping portal. That activity will reset the 18-month expiration clock, so if you aren’t quite ready to redeem your miles, you don’t need to hurry.Instead of calling, try booking awards to Jamaica on AA.com.

If you already have one, you can simply use it to make a purchase, and your expiration date will reset when the miles post to your account.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

The card carries a $450 annual fee, but depending on how large your family is, you could end up with enough miles to fly first-class to Jamaica, or enough miles to get you and your family anywhere in the world in economy. Just be flexible with your dates and you should be able to book online without even having to call.If you have any other questions, please tweet me @thepointsguy, message me on Facebook or send me an email at info@thepointsguy.com.
