Until August 31, 2015, United is selling miles up to 50% off.

The exact maximum discount is targeted, so you have to sign in to see your discount. My maximum discount is 50%. Even if you get the 50% discount, it only applies to purchases of at least 50,000 miles. United miles normally cost 3.76 cents each, so with a 50% discount, they cost 1.88 cents each.

After the 50% discount, 50,000 miles cost $941.

SPG Starpoints now transfer to 33 airlines with the addition of Korean SkyPass Miles to the list. Korean SkyPass is a 1:1 transfer partner, and, as with all 1:1 transfer partners, for every 20,000 points transferred, you get 5,000 bonus miles.

Examples:

15,000 Starpoints = 15,000 Korean miles
20,000Starpoints = 25,000 Korean miles
25,000 Starpoints = 30,000 Korean miles
60,000 Starpoints = 75,000 Korean miles

You can transfer Starpoints to airline miles here.

Transfer hotel points to United miles by August 31, 2015 for a 25% bonus of United miles.

The bonus is capped at 20,000 bonus United miles.
Here are the participating hotel points partners.

All of the hotel partners offer a terrible rate except for Marriott.

A few weeks ago, I used 27,500 Asiana miles (transferred from 22,500 Starpoints) to book myself a Business Class award from Honolulu to Bogota, Colombia. Now I'll tell you how to change an Asiana Club award.

I chose to use Asiana miles because it has a number of ridiculously cheap sweet spots including from Hawaii to South America.

This contest is closed. Geoff found a second pair, so four passes were sent to two winners. Check back most Fridays for a free giveaway.

Generous reader Geoff is donating two United Club passes that expire October 31, 2015–in 2.5 months–to one lucky winner. If you can use the passes between now and the end of October, enter.

United has lounges all over the world. The clubs are a pleasant place to relax in a comfortable chair, use free wifi, and enjoy free snack and drinks. Here are the amenities.

Alaska Airlines miles can be used to book a diverse array of oneworld, SkyTeam, and non-alliance partners.

I've written about some of my four favorite Alaska miles redemptions here, and I want to expand on one of those options.

These Award Wallet code giveaways sometimes get complaints. Unfortunately I don’t think there is any way to improve them.

Last month American Airlines announced it would fly from Los Angeles to Sydney beginning December 17, 2015. Even after it starting selling tickets and AAnytime (expensive) award space, it hadn't released a single MileSAAver award seat in any cabin in either direction as of a few weeks ago.

American Airlines is now releasing good economy award space on the route, especially from Los Angeles to Sydney. It still has released no Business Class or First Class award space.

Economy MileSAAver award space between North America and Australia/New Zealand is 37,500 American Airlines miles one way.

There's another hotel card with a temporarily increased sign up bonus.
