How to change or cancel an EVA Air award ticket
EVA Air Infinity MileageLands is EVA Air's frequent flyer programme, and the awards its miles buy — tickets, cabin upgrades and upgrade certificates — sit inside membership terms that let EVA Air correct, cancel or reclaim an award at any time, and require a member to repay the value of an award already received, when the award does not match what the rules allow. [2] [3]
Facts checked: 18 October 2026
Key takeaways
- Infinity MileageLands award miles can be spent on tickets, cabin upgrades and other award items, and those awards are governed by the programme's membership rules. [2] [3]
- The terms let EVA Air correct, cancel or reclaim an award when what a member holds does not match what the rules allow, at any time and without prior notice. [3]
- Miles run for 36 months from the flight date or the partner point-transfer date, then lapse without further notice. [2] [3]
- Where a partner provides the flight or the benefit, the partner's own published rules and terms apply. [3]
Which rules govern an EVA Air award ticket?
Award miles in Infinity MileageLands are the miles credited for EVA Air and UNI Air international flights, Star Alliance partner flights, Star Alliance connecting-partner flights, purchases through hotel, car-rental and credit-card partners, and birthday offers; the programme says they can be redeemed for tickets, cabin upgrades and other award items. [2] The membership terms group award tickets, cabin upgrades and upgrade certificates together as award items that the membership rules and the rules of the relevant activity govern. [3]
An award ticket also earns nothing back. For travel on EVA Air and UNI Air, the programme lists discounted and preferential tickets — award tickets and free tickets among them — as fares that do not accrue award miles, status miles or flight sectors. [2]
Miles have a fixed life: 36 months from the date of the flight, or from the date a points transfer is requested through a partner's system, and miles that reach the end of that period lapse automatically with no separate notice. [2] [3]
When can EVA Air cancel or reclaim an award?
The terms give EVA Air a wide correction right. Where mileage accrual, an award such as an award ticket, cabin upgrade or upgrade certificate, a member offer or another benefit does not match what the member was actually entitled to under the rules and the relevant activity rules, or where anything is irregular or improper, EVA Air may correct, cancel or reclaim it at any time without prior notice and without liability. [3] The measures listed include requiring the member to make up a shortfall in miles, correcting or removing miles or certificates, cancelling a redeemed award and cancelling the transaction. [3] EVA Air may also require a member to repay the value of an award already redeemed or received, at a value the airline itself determines. [3]
Trading sits outside the rules. Members may not buy or sell membership benefits, including miles, upgrade certificates and other benefits, and where an investigation finds or suspects a breach EVA Air may suspend or cancel the membership and its benefits, and reclaim miles already transferred or used, tickets already redeemed and awards already obtained. [3] Spreading or encouraging a breach is treated the same way, as is asking another person to act on a member's behalf. [3]
Ending a membership ends the balance. When a membership terminates, EVA Air does not keep the account: accumulated miles and electronic upgrade certificates are voided and the related benefits end at the same time. [3]
Where do you handle the ticket side and the mileage side?
EVA Air separates the two jobs on its website. The Infinity MileageLands menu carries award and upgrade availability, mileage redemption, transfer and return of miles, reinstating miles, and electronic certificate management, while the trip-management area carries change dates/flights, cancel booking, refund application/inquiry and a no-show charge. [4]
Reinstated miles count as a member's own miles: the terms say miles received as a gift cannot be combined for use with the member's own miles, meaning the ones the member earned, purchased and reinstated. [3] Account management also holds a nominee list and electronic certificates, which is where upgrade certificates live. [4]
Do Star Alliance partner awards follow the same rules?
Partner awards follow the partner. EVA Air defines a partner as an independent airline, bank, car-rental company, hotel or other entity that offers members products, services or benefits, including entities that let members buy, accumulate or redeem miles, and says the partner's own published rules and terms apply to what the partner provides and should be read before accepting. [3] EVA Air and its affiliates take no responsibility for partner products or services, and the miles, status or other benefits a member receives through a partner may vary with membership status or other factors. [3]
Star Alliance is the grouping EVA Air's own rules name when they discuss partner flying, and sectors flown on Star Alliance member airlines cannot be credited toward membership upgrades and renewals. [5] For a partner-operated award, the partner's terms are the ones that govern what the partner supplies. [3]
Exceptions and limits
- EVA Air-issued awards only. This page describes awards issued by EVA Air from Infinity MileageLands miles; where the product or service comes from a partner, the partner's own rules and terms apply. [3]
- Corrections can arrive without notice. The rights to correct, cancel and reclaim are exercisable at any time and without prior notice, and EVA Air disclaims liability for them. [3]
- Expired miles are not held. Miles that reach the end of their 36 months lapse automatically, without a separate notice to the member. [2] [3]
- Account suspensions. EVA Air may audit an account without prior notice and suspend some or all account functions; accumulated miles, upgrade certificates and awards may be unusable and may expire during a suspension, and a member who has not broken the rules may use what is left and still valid once the suspension ends. [3]
- Status flying is counted separately. Star Alliance member-airline sectors do not count toward Infinity MileageLands upgrades or renewals. [5]
Frequently asked questions
Can EVA Air cancel an award ticket after it is issued?
Yes, in the situations the membership terms describe: where an award or mileage balance does not match what the rules allow, or where anything is irregular or improper, EVA Air may cancel or reclaim it at any time without prior notice and may seek repayment of its value. [3]
How long are the miles behind an EVA Air award valid?
Miles are valid for 36 months from the flight date, or from the date a points transfer is requested through a partner's system, and then lapse automatically. [2] [3]
Do EVA Air award tickets earn miles?
No. Award tickets and free tickets are listed among the discounted and preferential fares that do not accrue award miles, status miles or flight sectors on EVA Air and UNI Air flights. [2]
Do Star Alliance partner awards follow EVA Air's rules?
What a partner supplies is governed by that partner's own published rules and terms, which EVA Air says members should read before accepting. [3]
