Joining JAL Mileage Bank is free, takes about ten minutes online, and your JMB number is issued at the end of the form — there is no enrolment fee and no annual fee, and you do not need to fly first or hold a credit card. Japan Airlines states plainly on its JMB enrolment page that there is no registration fee, no membership fee and no annual fee, and that applications are accepted online at any hour.
The part that catches people out is not the form. It is the two rules that sit behind it: your name has to match your passport exactly, and a brand-new account cannot book award tickets straight away. Both are covered below.
What JAL Mileage Bank actually is
JAL Mileage Bank (JMB) is Japan Airlines' frequent-flyer programme. It is a free loyalty account that collects miles when you fly and lets you spend them on award flights and upgrades. Japan Airlines explains the structure on its How JMB Works page.
It is not a credit card, and this is the single most common misunderstanding about it. Japan Airlines separately sells co-branded "JAL Card" credit cards that earn miles on everyday spending, but those are a different product with their own fees. You do not need one to join JMB, to hold miles, or to book an award. Membership itself costs nothing.
Is a JAL Mileage Bank account free?
Yes, and it stays free. There is no joining fee, no annual fee and no requirement to buy a ticket to keep the account open. The only cost that ever attaches to a JMB membership is if you choose to take out a JAL Card credit card, which is optional and separate.
How to create a JAL Mileage Bank account, step by step
- Open the enrolment form. Japan Airlines runs online enrolment at its JMB enrollment page. You can also reach it from the Mileage menu on the JAL site by choosing "JMB online enrollment" under the About JMB category.
- Read and accept the JMB Rules and Conditions. You cannot progress past this step without accepting them, and they are the document that governs everything below.
- Enter your name exactly as it appears in your passport. Not a shortened version, not a preferred name. See the warning below — this is the step that costs people miles.
- Fill in your date of birth, email address and postal address. The address determines which regional version of the programme you are enrolled under.
- Set your language and statement preferences, then submit.
- Save your JMB number. It is issued on completion and it is the thing that links every future flight to your account. Put it somewhere you will still be able to find it in two years.
The name-matching rule that costs people miles
Enter your name character-for-character as it is printed in your passport, in the same order. If your JMB profile says "Dave Smith" and your ticket says "David John Smith", the flight may not credit automatically, and an award booking in a name that does not match your ID can be refused at check-in.
This is worth getting right at enrolment because correcting a name on an existing frequent-flyer account is a manual process handled by customer service, not something you can simply edit yourself. Ten seconds of care on the form saves a support ticket later.
If you have already made this mistake, you are not stuck — see the section on claiming missing miles below, which is the mechanism for recovering flights that failed to credit.
The waiting period before you can book an award
A brand-new JMB account generally cannot book award tickets immediately. The widely-reported rule is a waiting period of around 60 days from enrolment before award booking opens up, and members who transfer points in from certain partner credit-card programmes report a much shorter wait. Japan Airlines publishes the governing conditions in its notes on using JAL International Award Tickets, which is the authority to check against your own account rather than any figure quoted second-hand.
The practical takeaway does not depend on the exact number: open the account well before the trip you want to book with miles, not the week you plan to travel. Enrolment is free and takes ten minutes, so there is no reason to wait until you need it.
Joining from the UK, the US or anywhere outside Japan
You do not need to live in Japan. JMB is open to members worldwide — you select your country or region during sign-up, which determines your regional programme terms and the language of your correspondence. Miles earned are the same miles wherever you enrolled.
One thing to be aware of: some JMB services and promotions are restricted to members registered in particular regions, and the co-branded JAL Card products differ substantially by country. The core account — earning, holding and redeeming miles — works the same everywhere.
What to do in your first week as a member
- Add your JMB number to every booking you already hold on Japan Airlines or a oneworld partner. Doing it before you fly is far easier than claiming afterwards.
- Claim any recent flights that did not credit. Japan Airlines accepts post-flight credit requests for up to six months after the flight date, and will also consider flights flown before you joined if the request is made within that window. The process is on JAL's post-flight credit page. If you flew JAL or a partner in the last few months, this is free miles you already earned.
- Diarise your mile expiry. JMB miles are valid for 36 months, expiring at the end of the 36th month after the month you earned them, per JAL's mile validity page. Unlike some programmes, activity on the account does not reset that clock.
Where the account goes from here: FLY ON status
Miles and status are two separate currencies in JMB, and mixing them up is a common source of confusion. Miles are what you spend on awards. FLY ON Points are what earn you elite status, and they are counted separately over a calendar year.
JAL publishes the qualification thresholds on its FLY ON membership levels page. Broadly, JMB Sapphire — which carries oneworld Sapphire benefits such as lounge access — requires around 50,000 FLY ON Points including 25,000 on JAL Group flights, or an alternative flight-count route. JGC Premier sits higher at roughly 80,000, and Diamond at roughly 100,000. Check the current figures on that page before you plan a status run; these thresholds are reviewed and they carry conditions about how much must be flown on JAL Group metal.
For most people opening an account to credit a single trip to Japan, status is not the point. Knowing the two currencies are different is.
