This is the nineteenth post in a monthlong series that started here. Each post will take about two minutes to read and may include an action item that takes the reader another two minutes to complete. I am writing this for an audience of people who know nothing about frequent flier miles, and my goal is that by the end, you know enough to fly for free anywhere you want to go. Previously Using to Search for American Airlines Awards. is a frustrating, broken piece of junk, but it’s the first place to start when looking for award reservations with your Delta SkyMiles on flights operated by Delta, Air France, KLM, Virgin Australia, Alitalia, or Korean.

On the home page, type your departure and arrival airports into the flight search box. I always search one way on searches because it is so bad at pricing awards that I don’t want to give it the chance to try adding the outbound and return’s cost.

Make sure to check the boxes that says Book award travel and My dates are flexible.

What are the other tricks to searching What are Delta’s routing rules?

Because we checked that our dates are flexible, we’ll come to a color-coded calendar that shows which of the three miles prices each day has. We are only interested in green low-priced flights.

All January 2014 JFK to Tel Aviv flights are priced at the high level price of 350,000 miles per ticket.

To toggle to business availability, click First/Business on the Calendar.

All January 2014 business class seats are at the High Price (in miles) also unfortunately.

As you can see, Delta’s availability on its own flights is often putrid. You’ll see a lot of yellow (medium) and blue (high) days. We want the green (low) days to get the most value for our miles.

You can toggle months on calendar by clicking the red arrows. There are some low-level (green) priced tickets in May on the route in economy.

Select a day with low level priced mile tickets, and you’ll be shown the possible itineraries, ordered from shortest to longest duration.

Click Show Details for more info on the flight.

Once you are looking at a single day’s options, the lowest priced itinerary should have a yellow coloring in the price box. To ensure you are looking at a low-miles-price itinerary, consult the SkyMiles award chart.

Double whatever the chart says in the appropriate column since Delta charges the roundtrip price for oneways. The low roundtrip economy class price from the USA to Israel is 80k miles, so the above itinerary is the low miles price.

If you’ve found low-miles-price space, note the date, time, and flight number, then do a search for the return leg.

If you don’t like what you’re seeing on a day, you can always get back to the award calendar by clicking View Award Calendar on the left. And once there, you can toggle the cabin choice.

Once you’ve found each suitable segment of your itinerary through one way searches, you can piece together those flights on a roundtrip or multicity search and purchase online.

Unfortunately using often does not go according to plan. is a piece of junk that mis-displays how many miles are needed for certain trips, doesn’t show all partner options, and generally doesn’t work well. When you’re having trouble, you can call Delta at 800-323-2323 to search availability or make a booking.

I use to search Delta, Virgin Australia, Air France, KLM, Alitalia, and Korean space. Korean space isn’t searchable anywhere else. Virgin Australia space isn’t convenient to search elsewhere. Air France and KLM have stopped releasing all their space to Delta, so is the only place to figure out what space Delta has.

One huge annoyance about searching Korean and Virgin Australia space is that the calendar view doesn’t factor it in, so you have to search day-by-day.

Example: There is space on June 7 from LAX to Sydney at the Low Price. (Yes, Delta charges 100k roundtrip for this route in economy. US Airways charges 110k roundtrip for this route in business, with a stop in Asia if you want.) But the Delta flight is at the medium price of 140k roundtrip.

As you can see, the calendar only takes the Delta space into account, listing June 7 as a Medium Price day.

So if you want to book on Korean or Virgin Australia, ignore the calendar and search day-by-day.

You have to know about, and occasionally you have to use it. But I also do a lot of my award searches on Expert Flyer when I want to use my Delta miles. More on that tomorrow.

Routing Rules

Searching for award space is great, but don’t forget that the space you find has to be pieced together to satisfy Delta’s routing rules. See here for Delta’s routing rules.
