Starwood Preferred Guest is a hotel loyalty program, but it’s different from other hotel programs. It allows members to transfer Starpoints to most of its 36 partner airlines at a 1:1 ratio. Plus, you’ll get a 5,000-mile bonus for every 20,000 Starpoints you transfer to a frequent flyer program.

We explained the best and worst redemptions for American Express Membership Rewards through the Amex Travel Portal. Now we look at the value of those points when transferred to frequent flyer programs.

The Citi ThankYou program has 12 airline transfer partners, but none of them would be considered household names by Americans. Citi has members like Malaysia Airlines, Eva, Singapore and Virgin Atlantic, and many people don’t quite understand how to use these airlines to fly from the U.S. But this is where airline alliances are especially helpful.

While an award ticket to Asia on a United partner airline can be expensive, there are three main reasons that make it worthwhile. First there is the sheer number of partner airlines you have to choose from.

This flexible policy makes it possible to go to multiple destinations without spending more miles.

Its idyllic coastline, tropical climate, year-round festivals and relatively unknown status among tourists makes the Indian state of Kerala a near-perfect destination. Among the area’s appealing attributes are miles of tranquil beaches, myriads of ecotourism activities, unique local celebrations and access to ancient Ayurvedic healing practices.

Alaska Airlines has been busy this season. After recently announcing a codesharing agreement with Icelandair, which includes reciprocal frequent flyer perks, the carrier is now expanding its relationship with Emirates, a Dubai-based airline.

Delta Air Lines, in a partnership with Virgin Atlantic, is launching two new routes across the pond—a nonstop flight between Salt Lake City and London, and another from New York to Edinburgh. The new routes will start in May 2016.

Moorea is one of the Society Islands, an archipelago in French Polynesia. This beautiful and idyllic island, located a few miles off the northwest coast of Tahiti, is the perfect destination if you’ve always wanted to stay at a luxury tropical resort without blowing your budget. Moorea is less costly than its more famous cousin Bora Bora, but no less amazing. So get ready for your overwater bungalow experience, and get there with miles.

The Maldives is an archipelago of 26 coral atolls with over 1,000 islands. Only 200 of them are inhabited. They lie in the Indian Ocean, about an hour by plane from Colombo, the capital of Sri Lanka. In the last 40 years, the Maldives has transformed from a virtually unknown British colony to one of the most popular travel destinations in the world.

Although Flying Blue is touted as the frequent flyer program for Air France and KLM, several other airlines also use the program, including Air Europa, Kenya Airways and TAROM.

Aerolineas Argentinas, the country’s flag carrier, is the largest airline in Argentina, flying to 24 cities in 14 countries. The airline also has an extensive domestic network connecting Buenos Aires to 35 cities. From its hub in Buenos Aires, it flies to two U.S. destinations: Miami and New York.

In the world of points and miles, Aer Lingus is an oddity, like neighbor British airline Virgin Atlantic. It’s a major player with key partnerships with other major players, but it’s not a part of any of the big alliances, though it was formerly with oneworld.
