Miles Calculator
Which fare classes earn full miles? The 100% club on six Star Alliance airlines
Figures checked October 17, 2026
Two passengers sit side by side on the same Singapore Airlines flight. One earns 6,765 miles for the trip and the other earns 3,383, because their tickets carry different fare class letters. The seat is the same and so is the distance. The fare class letter on your ticket decides how many miles you get, and our calculator shows the earning for every class.
The short version
- "Earning 100%" means you get one mile for every mile flown. Higher classes earn more: 125%, 150%, and 200% or more in first. Cheaper ones earn less.
- The cheapest economy tickets earn 25% to 50% on these six airlines, and 25% on Turkish, Thai and Air China.
- The same letter means different things on different airlines. Letter S is premium economy at 125% on Singapore Airlines and plain economy at 50% on ANA.
- The letter is on your booking confirmation. Look it up before you book, because the cheapest fare on a flight is often the one that earns almost nothing.
Economy: who is in the 100% club
These are the economy letters (premium economy, business and first are in the next section). A class earns 100% when you are credited with at least the distance flown. Thai Airways is the most generous: letter H earns full miles, and so do Q and T. Singapore Airlines needs a flexible fare (B, E or Y), and EVA Air needs its top economy fare.
| Airline | 100% or more | Below 100% |

| Singapore Airlines | 100% B E Y | 75% H M W50% K N Q V G |
| Turkish Airlines | 125% Y B100% M H S E Q A O | 50% T L V G25% W P F U |

| Air China | 110% Y B100% M | 75% H Q U V50% S T W25% K L P |
Percentages are of the distance flown, on long-haul international flights. Turkish adds a minimum number of miles per flight, which helps on short trips. Air China counts kilometers.
One letter, six answers
Fare class letters are not standard, and every airline sorts them its own way. Here is each economy letter on each airline. Green means 100% or more, and red means 30% or less. Where a letter is in a higher cabin, the cabin is named in the cell.
| Letter | Singapore Airlines | Turkish Airlines | ANA | Thai Airways | EVA Air | Air China |
|---|---|---|---|---|---|---|
| Y | 100% | 125% | 100% | 110% | 100% | 110% |
| B | 100% | 125% | 100% | 110% | 100% | 110% |
| M | 75% | 100% | 100% | 110% | 75% | 100% |
| H | 75% | 100% | 70% | 100% | 75% | 75% |
| Q | 50% | 100% | 70% | 100% | 75% | 75% |

| W | 75% | 25% | 50% | 25% | 50% | 50% |
Letter M earns full miles on Turkish, ANA and Air China, 110% on Thai, and only 75% on Singapore Airlines and EVA Air. Letter S is the biggest gap of all: 125% on Singapore Airlines, where it is a full-fare premium economy ticket, but 50% on ANA, EVA Air and Air China. A dash means the airline's chart doesn't use that letter.
Every cabin, side by side
This is the range of earning in each cabin. The spread inside a cabin is wide, so a business ticket is not automatically a big earner.
| Airline | Economy | Premium economy | Business | First |
|---|---|---|---|---|
| Singapore Airlines | 50% to 100% | 100% to 125% | 125% to 150% | 200% |
| Turkish Airlines | 25% to 125% | – | 135% to 150% | – |
| ANA | 30% to 100% | 70% to 100% | 70% to 150% | 150% |
| Thai Airways | 25% to 110% | 110% | 125% to 150% | 200% to 250% |
| EVA Air | 50% to 100% | 100% to 125% | 125% to 175% | – |
| Air China | 25% to 110% | 90% to 110% | 125% to 250% | 250% to 300% |
The fare you buy within a cabin can matter as much as the cabin. Turkish economy runs from 25% on its cheapest fare to 125% on its full fare, a wider spread than the step from full-fare economy to its cheaper business class at 135%.

The traps to avoid
- The cheapest economy letters. Turkish W, P, F and U, Thai W, and Air China K, L and P earn 25%. ANA L and K earn 30%. On a 5,000-mile flight, the 25% fares earn 1,250 miles.
- Miles but no status. On Singapore Airlines, class G earns KrisFlyer miles but no Elite miles, so it doesn't count toward Elite Silver or Gold. Check the KrisFlyer guide before you book it for status.
- A partner's flight earns by the operating airline's class. If you fly on a codeshare, the miles follow the booking class of the airline that operates the flight, which may differ from the letter on your ticket. The calculator's airline option shows the result for each program.
Programs that don't work by letter
- Air Canada Aeroplan is spend-based. Status Qualifying Credits are 4 per Canadian dollar on Flex fares and above, 2 on Standard, and none on Basic.
- United MileagePlus is spend-based too. Basic Economy earns Premier Qualifying Points but no Premier Qualifying Flights.
- Miles & More (Lufthansa, SWISS, Austrian and others) fixes status points per flight by cabin and by whether the flight crosses continents. The calculator uses 60 points for an intercontinental economy flight, 80 in premium economy, 200 in business and 400 in first.
- Other programs publish the earning only through their own calculators. We show an entry box for those, and you type in the figure.
How we worked it out
Every percentage is the share of the distance flown that the program credits for that fare class, as shown in the status calculator on October 17, 2026. The data comes from each airline's published charts, linked from the guides above. Rules change often, so check the date, and see the status targets page for the latest numbers.
Choose your program, pick the fare class from your booking, and see the miles and status progress for your route.
