You can see three "destination" cities on one United award, but you need to book a separate ticket with Avios or cash to tie the trip together.

Why is three the limit?
Why does seeing even three cities require a second award?
How can you see four or more cities with United miles?

You get one stopover and two open jaws on a roundtrip United award in addition to your destination and origin cities.

When you look at what possibilities that opens, you see that you can have three "destinations" on your award, kind of.

For instance, you can fly

Getting to the Big Island of Hawaii from the United States mainland is easy with miles. There are a ton of direct flights on several airlines, most of which have fantastic award space. Several of the flights can even be booked for as little as 12,500 miles each way.

I've been on the Kona side of Hawaii Island this week with my family, and it has been fantastic.

The snorkeling on this coast is the best I've ever experienced.

American Airlines has a unique routing rule that you cannot transit a third region on an award between two other regions. Under this rule, flying from the United States to the Middle East to Africa would require two awards, one from the United States to the Middle East and one from the Middle East to Africa.

Book these five awards before the US Airways Dividend Miles program disappears.

We know the program will end in early 2015, rolled into a new American Airlines loyalty program. I expect that combined program to be much worse than either the current American Airlines or US Airways program, which I love so much.

The two big reasons to love the US Airways program:
