The United shopping portal is offering 15 miles per dollar today only (until 11:59 PM ET on 1/22/17) at a number of stores that normally offer only 2-5 miles per dollar.

I value United miles at 1.6 cents each, so getting 15 miles per dollar on your purchase is like getting 24% of your purchase rebated back in United miles (in addition to the 1x or more you're getting on your credit card purchase normally.)

Here are the 15x stores:

You can no longer tack on an Excursionist perk, the essentially free segment within one region that United gives you on a "roundtrip", to the end of an itinerary any more.

A few weeks ago my United flight from Houston to Buenos Aires was delayed 13 hours. United automatically offered me 7,500 miles or $100 United credit as compensation, but I was able to increase that offer to 17,500 miles or $200 credit with a simple email.
The Delay
I was heading from the Chicago Seminars to my winter home in Buenos Aires. I booked the award for 30,000 United miles the week before departure using secret United award space.

Brussels Airlines is a partner of Etihad miles, and this is the amazing award chart for roundtrip redemptions, including 36,620 Etihad miles roundtrip in Business Class between New York and Brussels, or about a quarter of the miles United would charge for the same booking:

Brussels award space in Business Class is wide open on united.com for Summer 2017 at the moment, and Etihad miles are easy to get as a 1:1 transfer partner of Citi ThankYou Points and Amex Membership rewards, so I figured some serious investigation was in order.

How to Book a Brussels Airlines Flight

Nothing cries out for a BIG trip idea like a few weeks with nowhere to be.

I'm considering going from Hawaii to Croatia from mid-February to mid-March.

Last month, I booked an award from Buenos Aires to Honolulu for 25,000 Singapore miles and about $100 in taxes. The booking illustrates a few topics:

Sweet spots and how to find them
Awards you should book speculatively
Booking awards with foreign programs

The Problem
I have to get to Hawaii for my brother's wedding in February. The main problem is that I don't know where I'll be in February to book the ticket to Hawaii.
