Delta SkyMiles Calculator for DL-only flights

The Delta SkyMiles program is another one of the airline loyalty programs that has gotten rid of a defined award chart. The pricing of their award tickets now reflects the demand for a specific route. Nonetheless, we have tried to put together a calculator specifically for Delta flights. This calculator is based on experience and countless searches and is meant to give our users a general idea of what the rates should be. They are broken down into the various booking classes and show both minimum observed rates as well as average rates seen in the booking engine.

On the miles calculator page use the "Delta SkyMiles, DL flights only" calculator for these rates. Rates for flights with Delta's airline partners can be found in the  "Delta SkyMiles, only partner flights" calculator.

Unofficial Delta Partner Calculator

Delta SkyMiles award rates do not follow a fixed pattern (ie. there is no official award table), especially for flights with Delta Air Lines. However, redemption flights with Delta partner airlines follow a relatively stable pattern for Miles needed per flight. The rates are mostly zones based with some exceptions (e.g. miles prices for flights in South America seem to be distance based). The flights covered by this calculator do not include any flights operated by Delta proper. Select "Delta SkyMiles Partners" on the rates calculation page.

No More United Award Charts

The United Mileage Plus program stopped publishing award charts in the summer of 2020. It is therefore no longer possible for milez.biz to show completely accurate award rates on its website. We nonetheless continue showing United Mileage Plus calculators as we have made adjustments to reflect what seems to be the consensus on the miles required for award flights.

United’s own metal “saver” rates seem to have stayed mostly the same as before. These rates include flights with non-Star Alliance Partners as well. We have, however, removed the “standard” rates from our calculator. United's non-Star Alliance partner members airlines are the following:

  • Aer Lingus
  • Aeromar
  • Air Dolomiti
  • Azul
  • Boutique Air
  • Cape Air
  • Edelweiss Air
  • Eurowings
  • Hawaiian
  • Olympic
  • Silver Airways
  • Vistara

Star Alliance award rates have been devalued across the board by 10%. This also affects itineraries that include United Airlines flights.

Aeroplan Relaunched

Air Canada’s Aeroplan program has been redesigned and relaunched in November 2020. The relaunched program still has award rate tables but they are now a blend of zone-based rates and distance-based rates. We have adjusted the milez.biz code and data so it would accommodate the new calculations. 

Aeroplan used to divide the world into 15 geographical zones; the new program only has four zones. In other words, many zones were amalgamated. This brings both advantages and disadvantages to the miles cost of award flights. Generally speaking, flights across an ocean now cost a little more due to mile devaluation. However, flights within a zone can in some cases be significantly less expensive, especially where multiple zones were merged into one zone. 

For example:
The lowest round-trip award rate for a flight in economy between North America and Europe is now 70,000 miles. This used to be 60,000 from anywhere in North America to the Europe I Zone, e.g. an award ticket from Los Angeles to Vienna. That same redemption is now 110,000 miles due to the long distance between the destinations. 

On the other hand, travelling from Rome to Cairo used to cost 45,000 miles for a round trip ticket in economy. Now, this rate has dropped to only 25,000 miles because the two destinations are within the same Atlantic Zone and relatively close to each other (and there is a direct flight).

There are many more examples like that. The sweet spots will be found between destinations in the same zones that used to be in distinct zones, especially if there are direct flights or where the connecting airport is along the route, geographically speaking. For example, an award flight from Austin, TX, to Havana, Cuba, used to cost 40,000 miles round-trip in economy; now, even with the connection in Houston, the round-trip is only 20,000 miles. 

One of the key changes to the Aeroplan program is the removal of the fuel surcharges. Certain airlines like Air Canada, Lufthansa and Austrian used to charge very high fuel surcharges on award tickets, which made redemptions on those airlines very unattractive. These have been eliminated so that even with the somewhat higher award rates it may now be worth using your miles on flights with those airlines. 

Another novelty is that you can now interrupt one-way itineraries. This was not possible in the old iteration of Aeroplan. There is a 5,000-mile cost associated to a stopover but this may be a very attractive option for many travellers. 

The old Aeroplan award rates are no longer valid. However, we will leave the old calculator up and running for a few weeks so that you can compare the rates and find awards tickets that may be a better deal now. The new Aeroplan calculator on milez.biz includes all the Star Alliance carriers as well as the Aeroplan partner airlines: Etihad, Canadian North, GOL, Azul, Air Serbia, Air Creebec, Olympic, Eurowings, Vistara and Juneyao.
