United Arlines is offering a discount on miles purchased directly from them here.

Each discount seems to be personalized to your account (I got up to 40%), but I see some users online getting up to 100%. Check your account for the specific numbers.

You can buy up to 175,000 miles in a year.

Why buy Miles?

You can use United miles for great value for international travel!

You can fly to Europe or Asia for 80-90K miles in business.I usually find at least 1 or 2 days a month.

When Does the deal expire?

Aug 25th!
