Turkish Airlines now requires more Miles&Smiles miles to upgrade its lowest-priced EcoFly Economy fares to Business Class than it charges passengers booked on other Economy fare packages. The difference varies by region, but it is especially noticeable on long-haul routes involving North America and the Far East, where an EcoFly upgrade now costs 90,000 miles one-way compared with 65,000 miles for other Economy packages.
The revised structure means that selecting the cheapest Economy package can have implications beyond the original cash fare. Travelers who expect to use Miles&Smiles miles for a later Business Class upgrade now need to consider both the initial ticket price and the additional mileage requirement attached to EcoFly.

Turkish Airlines now has separate mileage requirements for EcoFly-to-Business Class upgrades and upgrades from other Economy Class packages to Business Class.
Previously, travelers comparing Economy fares might primarily have focused on differences in ticket conditions and included services. The updated upgrade chart adds another factor: the number of miles required to move into Business Class.
Turkish Airlines’ current one-way upgrade chart is:
| Region From/To Türkiye | EcoFly to Business | Other Economy Packages to Business | Additional EcoFly Cost |
| Türkiye | 12,000 miles | 10,000 miles | 2,000 miles |
| Europe 1 | 22,000 | 20,000 | 2,000 |
| Europe 2 | 27,500 | 25,000 | 2,500 |
| Central Asia | 38,500 | 35,000 | 3,500 |
| Middle East | 32,500 | 28,000 | 4,500 |
| North Africa | 44,000 | 40,000 | 4,000 |
| Central Africa | 65,000 | 60,000 | 5,000 |
| Southern Africa | 80,000 | 75,000 | 5,000 |
| Far East | 90,000 | 65,000 | 25,000 |
| North America | 90,000 | 65,000 | 25,000 |
| South America | 80,000 | 75,000 | 5,000 |
| Oceania | 110,000 | 100,000 | 10,000 |
These figures apply to one-way upgrades on Turkish Airlines flights.
The largest increase applies to travel between Türkiye and North America or the Far East.
An EcoFly passenger on one of these routes needs 90,000 Miles&Smiles miles for a one-way Business Class upgrade. A passenger holding another eligible Economy package needs 65,000 miles.
That produces a difference of 25,000 miles per direction.
For example, an eligible EcoFly passenger traveling between Türkiye and North America would need 90,000 miles for the upgrade. Under another eligible Economy package, the requirement would be 65,000 miles.
The difference becomes even more significant when considering 2 flight directions. Assuming eligible upgrade availability in each direction, the mileage difference would reach 50,000 miles across a round trip.
The additional mileage requirement is not uniform across the Turkish Airlines network.
For shorter regional trips, the difference can be relatively modest. An EcoFly upgrade between Türkiye and Europe 1, for example, requires 22,000 miles instead of 20,000—a difference of 2,000 miles.
Long-haul routes can have a much larger gap.
The EcoFly premium is:
Depending on the region, the difference ranges from 4,000 to 5,000 miles:
The largest difference appears here:
EcoFly passengers need:
The mileage difference therefore matters much more on certain long-haul itineraries than on short regional journeys.
EcoFly is one of Turkish Airlines’ Economy fare packages and is generally positioned as the more basic option within the airline’s package structure.
Turkish Airlines uses fare packages such as EcoFly, ExtraFly, and PrimeFly, with different conditions and included benefits. Package availability and exact conditions can vary according to whether the journey is domestic or international and according to the applicable market and ticket conditions.
The lower upfront price of a basic fare can be attractive when additional flexibility or services are not required. However, the revised mileage-upgrade structure gives travelers another reason to examine the complete fare conditions rather than selecting a ticket based only on its cash price.

The change is particularly relevant to travelers who purchase Economy tickets with the intention of upgrading later using Miles&Smiles miles.
A cheaper cash ticket does not necessarily mean the lowest combined cost once mileage requirements are considered.
Consider an eligible long-haul itinerary between Türkiye and North America:
A traveler choosing EcoFly might save money when purchasing the original ticket but later need considerably more miles to move into Business Class.
The value of one option versus another therefore depends on the original fare difference, the traveler’s available mileage balance, applicable fare conditions, and whether an upgrade is actually planned.
Miles&Smiles members can use miles to move eligible tickets into Business Class.
Turkish Airlines states that its Upgrade with Miles feature is available to Miles&Smiles members and can be completed through the airline’s website or mobile application. It applies to eligible paid and award tickets.
For a regular Upgrade with Miles transaction, the flight must be operated by Turkish Airlines. The program does not apply in the same way to codeshare flights operated by another carrier.
Turkish Airlines also states that a standard Upgrade with Miles transaction must generally be completed at least 24 hours before departure. Inside the final 24 hours, a separate Last Minute Upgrade option may be available, subject to seat availability and applicable conditions.

A mileage upgrade changes more than the seat at the front of the aircraft.
According to Turkish Airlines’ Miles&Smiles upgrade rules, travelers completing an eligible Upgrade with Miles receive the baggage allowance and lounge access associated with the upgraded cabin.
However, mileage earning on a paid ticket remains based on the Economy fare class in which the original ticket was issued rather than the upgraded Business Class cabin.
This distinction is important because a cabin upgrade does not automatically transform every element of the original fare into the equivalent of a Business Class ticket purchased outright.
No. Having enough Miles&Smiles miles does not necessarily mean a Business Class upgrade will always be available.
Upgrade transactions are subject to applicable eligibility and availability conditions. Last Minute Upgrades, for example, depend specifically on having an available seat on the requested flight.
Therefore, purchasing an Economy fare solely on the assumption that an upgrade will later become available can involve some uncertainty.
Travelers planning around an upgrade should review availability and current Miles&Smiles conditions before relying on that strategy.
The published Turkish Airlines mileage amounts apply to one-way tickets/upgrades.
That distinction matters when estimating the mileage required for an entire journey.
For example, using the published North America figures:
| Upgrade Scenario | EcoFly | Other Economy Package |
| One-way | 90,000 miles | 65,000 miles |
| 2 directions* | 180,000 miles | 130,000 miles |
| Difference | 50,000 miles | — |
*This calculation simply doubles the published one-way requirement and assumes the traveler has eligible flights and upgrade availability in each direction.
A traveler considering upgrades for an entire round trip should therefore calculate each direction rather than treating the published figure as a round-trip price.
The revised mileage chart creates a clearer distinction between EcoFly and other Economy packages.
| Factor | EcoFly | Other Economy Packages |
| Economy positioning | More basic fare package | Higher Economy packages |
| Upgrade to Business with miles | Available when applicable conditions are met | Available when applicable conditions are met |
| Mileage requirement | Higher | Lower |
| Difference by region | 2,000 to 25,000+ miles on most listed routes | Baseline published upgrade rate |
| Biggest gap | North America and Far East | 25,000 fewer miles than EcoFly |
| Published rates | One-way | One-way |
The table does not mean a higher Economy package is automatically the better purchase. The cash-price difference between fare packages also matters.
Instead, the new mileage structure makes it useful to compare the cash fare and potential mileage cost together when an upgrade is part of the travel plan.
Yes, Turkish Airlines offers a Last Minute Upgrade option.
This service can allow Miles&Smiles members to move into Business Class during the final 24 hours before departure when space is available. Turkish Airlines states that the service can be accessed through web and mobile channels, its call center, and airport counters, although availability can vary for operational reasons at some airports.
A last-minute upgrade should not be treated as guaranteed because it depends on available Business Class space.

No. Turkish Airlines’ standard Upgrade with Miles and Star Alliance Upgrade Awards are separate programs with different rules and mileage requirements.
For Star Alliance Upgrade Awards on Turkish Airlines-operated flights, Turkish Airlines currently states that Economy tickets must be booked in Y or B fare classes to qualify for an Economy-to-Business upgrade. Star Alliance upgrades also have their own restrictions regarding eligible tickets, timing, codeshare flights, and participating carriers.
Travelers should therefore avoid applying Star Alliance Upgrade Award rules to the regular Turkish Airlines Upgrade with Miles chart.
The new mileage requirements make several factors worth checking before purchasing the lowest Economy package.
Compare the original fares. A higher Economy package costs more upfront, so the cash difference should be compared with the potential mileage savings.
Consider whether an upgrade is actually likely. Paying more for a fare solely to reduce a mileage-upgrade requirement may offer little benefit when no upgrade is planned.
Check the travel region. The EcoFly mileage premium differs significantly by destination. A 2,000-mile difference for Europe 1 is very different from the 25,000-mile difference for North America.
Review the complete fare rules. Fare packages can differ in flexibility and included benefits, not just mileage-upgrade pricing.
Check upgrade availability. Sufficient miles alone do not guarantee that the desired upgrade can be completed.
Turkish Airlines’ revised upgrade structure makes EcoFly more expensive in mileage terms for travelers hoping to move from Economy to Business Class. The impact is relatively modest on some shorter routes, but it becomes much more significant for long-haul travel.
North America and the Far East illustrate the biggest difference: an EcoFly upgrade costs 90,000 miles one-way, while another eligible Economy package requires 65,000 miles.
For travelers planning to remain in Economy, the change may have little practical effect. For those buying Economy with the intention of upgrading later, however, the mileage requirement is now another factor to compare alongside the cash fare, fare conditions, available Miles&Smiles balance, and upgrade availability.
Yes. Turkish Airlines’ current upgrade chart requires more miles for an EcoFly-to-Business Class upgrade than for upgrades from other Economy packages.
