Yes, ANA Mileage Club Miles do expire 36 months after they have been earned. Per the ANA FAQs page:
“Miles are valid until the end of the 36th month after accrual.”
Essentially, this means that if you earned miles on January 15, 2021, they will expire on January 31, 2024. There is no way to extend your miles' validity or reinstate them once they have expired. The only exception to this rule is if you are a top-tier ANA Diamond Service member. In this case, your miles will never expire.

COVID-19 Mileage Expiration Extension
Like a host of other airlines and travel industry loyalty programs, ANA suspended the expiration of its miles during the COVID-19 pandemic. If you have not done so already, all you need to do is register by March 31, 2023 to extend your miles and ANA SKY COINS due to expire between March 1, 2023 and March 31, 2023.
One thing to note is that, if you do register, your ANA miles will expire as scheduled. After this, your account will be credited the same number of miles back with an expiration date of March 31, 2024.
Earning ANA miles
Boosting your ANA mileage balance is relatively straightforward, and there is a host of ways to pick up ANA miles without leaving the ground. You can earn ANA miles in all of the following ways:
- Fly with ANA — both domestically in Japan and internationally.
- Take a flight with Star Alliance partners — including Lufthansa, United, and Turkish Airlines — and credit your flight to ANA.
- Credit flights to ANA from flights on non-alliance partners — including Etihad, Garuda, and Virgin Atlantic.
- Earn miles when booking hotel stays via ANA global hotels.
- Stay at partner hotels, including Hyatt, IHG, and Marriott Bonvoy.
- Earn miles for various activities at partner shops, including The Bicester Village Shopping Collection and NAKA Golf Academy.
- Shop through the ANA Global Mileage Mall.
- Rent a car through ANA Global Car Rental.
- Transfer hotel points to ANA miles from brands including IHG, Marriott Bonvoy, Shangri La, and World of Hyatt.
Boosting your ANA Points Balance
While ANA does not have any US-based co-branded credit cards allowing you to earn miles for everyday spending, you can transfer Membership Rewards Points to ANA Mileage Club miles. Transfers occur at a ratio of 1:1 in increments of 1,000 points. Typically, transfers take 2-3 working days to go through.
Alternatively, you can top off your account with Marriott Bonvoy points. Points only transfer at a 3:1 ratio and you need to transfer at least 3,000 points (1,000 miles). However, you can choose to transfer any exact amount above 3,000 points. That means you can transfer 6,486 Bonvoy points if you need exactly 2,162 additional ANA Mileage Club miles to book an award. Just note that transfer times can take between 4-7 days.
Our Take
Giving you 36 months before your ANA miles is on the generous end of the spectrum when compared with other programs. Couple that with the ability to boost your balance with transfers from Membership Rewards — plus some excellent award sweet spots — and ANA miles are an excellent option, especially if you regularly travel between the US and Asia or Japan.
