Singapore Airlines KrisFlyer is the frequent flyer program of Singapore Airlines, where you earn KrisFlyer Miles through flights, partner airlines, credit cards, and affiliated services. Separately, elite status is determined by Elite Miles — a different metric from redeemable miles.
The key concept:
- KrisFlyer Miles = what you spend (award flights, upgrades, partners)
- Elite Miles = what you accumulate to qualify for elite status
This is where EconoMile becomes practical: it lets you compare fares, estimated Elite Miles, and estimated KrisFlyer Miles side by side, including "efficiency" metrics like Elite Miles per $100 and miles per $100.

1) Two Different Metrics: KrisFlyer Miles vs. Elite Miles
KrisFlyer Miles (Redeemable)
KrisFlyer Miles are the spendable currency in the program. Typical uses:
- Award flights on Singapore Airlines and partner airlines
- Upgrades (subject to fare class and availability)
- Partner redemptions (rates and availability may change)
KrisFlyer Miles expire after 3 years from the date of earning, unless you hold an eligible co-branded credit card or maintain elite status.
Elite Miles
Elite Miles are used to qualify for KrisFlyer elite tiers (Elite Silver / Elite Gold). Even on the same itinerary, KrisFlyer Miles and Elite Miles can differ significantly depending on the ticket.
Important: Elite Miles are tracked on a rolling 12-month window, not a calendar year. This means your oldest Elite Miles drop off as each month passes.
Status Requirements
| Status | Required Elite Miles | Rolling Period | Star Alliance |
|---|---|---|---|
| Elite Silver | 25,000 | 12 months | Silver |
| Elite Gold | 50,000 | 12 months | Gold |
PPS Club is a separate premium tier based on revenue (S$25,000 spend for Solitaire PPS).
2) How Elite Miles Are Calculated
Elite Miles are calculated with a straightforward formula:
Elite Miles = Segment Distance x Earning Rate
The earning rate depends on the cabin and booking class of your ticket.
Earning Rates by Booking Class (Singapore Airlines Operated)
| Cabin | Booking Class | Rate |
|---|---|---|
| Suites / First | A, F | 200% |
| Business | C, J, Z | 150% |
| Business | D, U | 125% |
| Premium Economy | S, T | 125% |
| Premium Economy | R, L, P | 100% |
| Economy (Full / Standard) | B, E, Y | 100% |
| Economy (Flex) | H, M, W | 75% |
| Economy (Saver) | K, N, Q, V, G | 50% |
EconoMile shows the calculation breakdown, so you can see exactly which booking class earns what, and how distance and rate combine for each segment.
3) PPS Club: The Spending-Based Tier
In addition to the Elite Miles tiers, Singapore Airlines has the PPS Club — a separate prestige program based on revenue rather than distance.
- PPS Club: Qualify by spending S$25,000 on eligible SQ flights in a membership year
- Solitaire PPS: Higher tier within PPS Club, requiring S$50,000 or more
PPS Club members receive Star Alliance Gold benefits, priority services, and access to exclusive lounges. Since PPS Club is spending-based, it is not directly tracked by EconoMile's distance-based calculations.
4) Key Elite Benefits
Elite Silver (Star Alliance Silver)
- Priority check-in: Dedicated counters
- Priority boarding: Board before general economy passengers
- Extra baggage: Additional checked baggage allowance
- Priority waitlist: Higher waitlist clearance priority
- Upgrade eligibility: Eligible for complimentary upgrades (subject to availability)
Elite Gold (Star Alliance Gold)
In addition to Silver benefits:
- Lounge access: Singapore Airlines and Star Alliance partner lounges worldwide
- Extra baggage: Higher additional checked baggage allowance
- Priority baggage: Your bags arrive first
- Guaranteed economy booking: On SQ flights even when full (conditions apply)
5) Why EconoMile is Useful for KrisFlyer Planning
KrisFlyer planning gets complicated because:
- Earning can swing significantly by booking class (50% to 200%)
- Status optimization (Elite Miles) and award optimization (KrisFlyer Miles) don't always align
- The rolling 12-month window means timing matters for maintaining status
- Comparing routes and cabins across different fare levels is tedious without a unified view
EconoMile helps by showing:
- Estimated fare ranges
- Estimated Elite Miles and KrisFlyer Miles
- Efficiency metrics like Elite Miles / $100 and miles / $100
- (Where supported) cross-program comparisons
- Cross-cabin comparisons (Economy / Premium Economy / Business / First)
6) How to Use the Destination Overview Page (Singapore Roundtrip)
Page: https://econo-mile.com/en/sq/sin/roundtrip
This page is designed for quick screening. For each destination, you can compare:
- Price
- SQ: estimated Elite Miles and Elite Miles / $100
- SQ: estimated KrisFlyer Miles and miles / $100
- (Where available) other programs' metrics
A practical workflow:
- Start with Elite Miles / $100 if your goal is status
- Cross-check with price and travel practicality
- If your goal is award travel, focus on miles / $100
In the right-side panel, you can:
- Toggle one-way / roundtrip
- Change origin/destination
- Filter airlines
- Select the crediting program (where supported)
7) How to Read a Route Detail Page (Example: Singapore ⇄ Tokyo)
Page: https://econo-mile.com/en/sq/sin/roundtrip/tyo
7.1 Route Summary at Top
You'll see a route-level range summary:
- Fare range
- Estimated Elite Miles and efficiency
- Estimated KrisFlyer Miles and efficiency
This gives you an instant sense of how the economics change across ticket types and cabins.
7.2 Cabin Cards (Economy / Premium Economy / Business / First)
Each cabin card summarizes:
- Fare range
- Estimated Elite Miles and efficiency per $100
- Estimated KrisFlyer Miles and efficiency per $100
8) Flight List: Booking Class Matters
The flight list breaks down the route into ticket groups like:
- Economy (booking class Q / V / K / ...)
- Premium Economy (booking class P / R / T / ...)
- Business (booking class D / Z / J / ...)
...and shows for each:
- Fare (or fare range)
- Estimated Elite Miles
- Estimated KrisFlyer Miles
- Efficiency metrics (per $100)
9) Expand for Calculation Breakdown (Elite Miles + KrisFlyer Miles)
On supported rows, expanding a flight shows the estimated formula components:
For Singapore ⇄ Tokyo (Economy, booking class Q):
- SIN → NRT (class Q): 3,312 mi x 50% = 1,656 Elite Miles
- NRT → SIN (class Q): 3,312 mi x 50% = 1,656 Elite Miles
- Total: 3,312 Elite Miles
Note: Outbound and return may have different booking classes, resulting in different earning rates.
10) Recommended EconoMile Usage (Goal-Based)
If Your Goal is Status (Elite Miles)
- Compare options by Elite Miles / $100
- Narrow down to realistic itineraries (duration, connections)
- Long-haul routes tend to earn more Elite Miles (distance x rate)
- Remember the rolling 12-month window — plan your timing
- Then evaluate fare rules and booking constraints
If Your Goal is Redeemable KrisFlyer Miles
- Compare by miles / $100
- Consider your preferred redemption strategy (SQ award flights are highly sought-after)
- If available, compare crediting programs for the same route
If Your Goal is Elite Gold (Star Alliance Gold)
- Target 50,000 Elite Miles within a 12-month rolling window
- Singapore departures offer many long-haul options to Europe, the Americas, and Oceania
- Routes to London, New York, Sydney, and Tokyo provide substantial distance-based earning
- Consider Premium Economy for a balance of comfort and earning rate (100-125%)
Non-Flight Earning
KrisFlyer also offers limited non-flight earning of Elite Miles:
- Kris+, KrisShop, Pelago: 1 Elite Mile per S$1 spent
- Cap: Non-flight Elite Miles cannot exceed 20% of total required Elite Miles for tier qualification
This means flights remain the primary path to elite status, making EconoMile's flight-focused comparison especially relevant.
