Recently, I posted about how we can get amazing value from the fact that the Singapore Airlines KrisFlyer program considers Hawaii to be part of the same region as Central AmericaWe can also use this sweet spot for great value on travel to South America too!

On the Singapore Airline’s award chart, it costs fewer miles to fly between Hawaii and South America, routing through the continental United States, than it does to fly directly between the continental United States and South America.

On the Singapore award chart:

  • Continental Unites States to South America: 60,000 miles roundtrip in economy
  • Continental Unites States to South America: 100,000 miles roundtrip in business
  • Hawaii to South America: 50,000 miles roundtrip in economy
  • Hawaii to South America: 80,000 miles roundtrip in business

This is great news for people that live in Hawaii or South America, but it is just as good for people who live in the continental United States!

People who live in the continental United States can use this sweet spot to get a complete vacation to South America and two half trips to Hawaii, all on one award redemption, for fewer miles than simply booking a roundtrip award between the continental United States!

Singapore miles are some of the easiest to get, since Singapore is a transfer partner of Chase, American Express, and Starwood Preferred Guest.

Singapore Award Rules

As I laid out in my last post on Singapore sweet spots, the Singapore Airlines’ relevant award rules include:

  • Singapore does not allow a stopover on one way awards.
  • Singapore Airlines allows six segments per award.
  • Singapore allows one free stopover per roundtrip award and up to three additional stopovers for $100 each.
  • Singapore allows one open jaw per roundtrip award.
  • Singapore collects fuel surcharges on many awards, but no flights you would use for this award have fuel surcharges. United flights to Hawaii and South America and Copa and Avianca flights between the United States and South America are all surcharge free.

We’ll examine each of these rules in relation to an example routing. You can view Singapore Airlines’ full routing rules here.

Example Routing

To illustrate the sweet spot between Hawaii and South America, I am going to give an example itinerary for someone based in Houston.

For only 50,000 Singapore miles in economy or 80,000 miles in business plus $100 plus taxes, we can book:

  • Honolulu to Houston (free one way #1)
  • Stopover for months
  • Houston to Buenos Aires
  • Buenos Aires to Houston (roundtrip award)
  • Stopover for months
  • Houston to Maui (free one way #2)

One Way vs. Roundtrip

We have a valid round trip booking, ensuring we are not tripped up by the rule that we may not have a stopover on a one way award.

Number of Segments

We use five segments on our proposed award, which is less than the limit of six that Singapore Airlines imposes on their award redemptions:

  1. Honolulu to Houston
  2. Houston to Buenos Aires
  3. Buenos Aires to Houston
  4. Houston to Los Angeles
  5. Los Angeles to Maui

Due to the rule that we can only have six segments included on the booking, to take advantage of this sweet spot, your home airport must have direct flights to either Hawaii or South America so that you stay under six segments. All United hubs in the continental United States and all cities with direct Avianca flights to Colombia satisfy this requirement.


We have two stopovers (one free and one for $100). The first is between our flight from Honolulu to Houston and our flight from Houston to Buenos Aires. The second is between our flight from Buenos Aires to Houston and our flight from Houston to Maui via Los Angeles.

Our time spent in Buenos Aires is not considered a stopover because Buenos Aires is the destination of our round trip award.

The stopovers can be as long as we want them, subject to the fact that United only releases award space to Singapore up to 331 days out, and we need to book all our flights at once.

Open Jaws

We have one open jaw (starting the trip in Honolulu and ending the trip in Maui), which conforms to Singapore Airlines routing rule that allows one.

Award Variations

We’ve laid out a fantastic itinerary. However, there are some changes that we could make to the award to better suit our particular circumstances.

  • We could put together a similar award for the same number of miles in reverse if we wanted two half trips to South America and one roundtrip to Hawaii.
  • If, on our trip to Maui we wanted to stopover in Los Angeles, we could pay an additional $100 dollars for the privilege of an additional stopover.
  • If we wanted to minimize our cash out of pocket and not spend $100 for a second stopover on the route, we could book the flights from Houston to Maui within 24 hours of our arrival in Houston from Buenos Aires. We could either combine the two vacations into one big one or treat the flights to Maui as dummy flights and not fly them.

How to Book the Award

You’ll be using Singapore Airline miles to book flights on its Star Alliance partners: United, Avianca, and Copa. The easiest place to search for award space on all three is I searched for the example award for these dates:

  • Honolulu -> Houston (September 2014)
  • Stopover
  • Houston -> Buenos Aires (November 2014)
  • Buenos Aires -> Houston (November 2014)
  • Stopover
  • Houston -> Maui (April 2015)

Singapore phone agents will have access to all Saver award space you see when searching without signing in to your United account. (Logging in will show extra Saver space that is available only to people with a United credit card or elite status. Singapore can’t book that space.)

Like always, write down the flight numbers, dates, and cabins, so you can feed them to the Singapore customer service representative when you call to book your ticket. Remember, getting to Honolulu before the start of this award and getting back to Houston after arriving in Maui will not be included in this award. I’ve written a lot about the best ways to travel to Hawaii with miles and you can find those posts here.

The Search

While award space was available enough to make the trip work with some flexibility in economy, there was no availability at this time in business.

I started searching in chronological order with Honolulu to Houston in September 2014. Since I knew that there are direct flights on this route, I checked the box on the United search interface to only search nonstop flights.

Singapore Sweet Spot 2

Singapore Sweet Spot 3

There is availability every day except Saturdays in September on the red-eye flight back to Houston.

Singapore Sweet Spot 4

Next I searched the Houston to Buenos Aires route in November. Again, knowing that there was a direct flight offered on this route, I checked the box to search only for nonstop flights.

Singapore Sweet Spot 5

Singapore Sweet Spot 6

The availability for this route was very limited in November, but there were still some options.

Singapore Sweet Spot 7

Next I searched the return flight from Buenos Aires to Houston in November. My goal was to find a flight that gave us a 10 day vacation in Buenos Aires. Again, knowing that there was a direct flight offered on this route, I checked the box to search only for nonstop flights.

Singapore Sweet Spot 8

Singapore Sweet Spot 9

Luckily, there was good availability, especially in the later part of the month, allowing us to spend exactly 10 days in Buenos Aires.

Singapore Sweet Spot 10

Finally, I searched the Houston to Maui route in March 2015. This time, knowing that there was no direct flight offered on this route, I did not check the box to search only for nonstop flights.

Singapore Sweet Spot 11

Singapore Sweet Spot 12

While the availability in the beginning of the month is not good, there is a lot of availability in the latter part of the month.

Singapore Sweet Spot 13

Calling Singapore

We’re flying United and we’re searching, but we have to call Singapore to book since we’re using Singapore miles.

Singapore’s US call center is open 24 hours a day. The number is: (213) 404-0301. There is no telephone booking fee. Always clarify with the agent whether she’s quoting a price in US dollars or Singapore dollars.

As always, if an agent cannot book a flight for you or prices it at a higher price then you are expecting, simply hang up and call back for another representative.

After feeding the agent the flights I’d found, he quoted a price of 50,000 Singapore miles plus $186. That represented $86 in government taxes and $100 for the second stopover. As noted above, Singapore does not collect fuel surcharges on United flights.

Comparison with United Miles

Using Singapore Airlines KrisFlyer miles is also a better bet for flights to South America than using United Airlines miles, Singapore Airline’s Star Alliance partner and the operator of most of the flights we’ll look at booking to take advantage of this sweet spot.

For flights flown on United, United charges 60k miles in economy or 120k miles in business roundtrip between Hawaii and South America and 60k miles in economy or 110k miles in business roundtrip between the mainland US and South America. Plus, we can’t pay $100 for a second stopover using United miles.

Getting Singapore Miles

Getting Singapore miles is extremely easy now.

Citi ThankYou Points transfer 1:1 in 22-36 hours to Singapore miles. If I had all four types of points in this section, transferring ThankYou Points would be my first choice. This is the best ThankYou Points transfer partner.

Application Link: Citi Premier® Card

Chase Ultimate Rewards earned with the Chase Sapphire Preferred® Card transfer to Singapore KrisFlyer miles in a day or two.

American Express Membership Rewards transfer to Singapore KrisFlyer miles in a day or two.



Singapore Airlines has placed Hawaii and Central America in one region. Singapore Airlines charges less miles to fly between the Hawaii/Central America region and South America, routing via the continental United States, than it does to fly directly between the continental United States and South America.

If you live in the continental United States, you can use these facts to combine multiple Hawaiian and South American vacations into a single award for fewer miles than if booking them separately.

Singapore miles are easy to rack up since the airline is a 1:1 transfer partner of Chase and American Express.

Hopefully booking a similar award to the one laid out in this post will be easy for you. If not, hire the MileValue Award Booking Service to book your dream trip (or trips in this case!) for you.
