JAL Mileage Bank miles hard-expire after 36 months. No extensions. No reinstatements. No activity resets. That single policy trips up more new members than any other part of the signup process.
Most airline loyalty guides treat the application like the hard part. The application is free and takes about ten minutes. The hard part is what happens to your miles once they land in your account.
This guide is for the US-based traveler planning a Japan trip who wants to sign up for JMB, link a credit card, and start earning. The kind of person who Googles "JAL Mileage Bank application" and needs a straight answer, not a brochure.
Signing Up for JAL Mileage Bank Takes About Ten Minutes
The enrollment itself is painless. JAL charges no registration fee and no annual membership fee for a basic JMB account. Go to JAL's official JMB enrollment page, pick your region, and fill out the form.
The form asks for your full legal name (matching your passport), date of birth, mailing address, email, phone number, nationality, and preferred language.
Double-check your name spelling against your passport. A single wrong character can create a mismatch that delays mileage crediting for weeks.
Physical JMB Cards Are Gone
JAL stopped issuing new and renewed physical JMB cards on August 4, 2025. The membership is now digital-only through the JAL Mileage Bank app, which stores your membership number and lets you pay with JAL Pay for everyday purchases.
I think this shift caught a lot of 2024-era guide readers off guard, because dozens of articles still describe the two-to-six-week card delivery window.
That window no longer exists. The app (available on Google Play and the App Store) replaces the plastic card entirely.
If you already had a physical card, it still works as backup. But new members get a digital credential and nothing else.
Residents Outside Japan: Pick the Right Regional Portal
JAL runs separate regional enrollment portals. A US-based applicant should go through the JMB Americas path, not the Japan-domestic site. The Japan-domestic enrollment page defaults to Japanese and is built for residents of Japan with Japanese addresses.
Regional differences affect more than language. The promotional offers, partner earn rates, and even the credit card options differ by region.
A US-based member looking at the JAL USA Card (issued by First National Bank of Omaha) will find that card only through the US-specific portal.
The 36-Month Expiration Policy Changes Everything
This is the single biggest thing to understand before signing up. JAL Mileage Bank miles expire 36 months after the date they were earned or transferred. That clock starts ticking the moment miles hit your account.
No activity-based resets. No paid extensions. No reinstatement after expiration. Compare that to Delta SkyMiles or JetBlue TrueBlue, where miles never expire at all.
Why "Transfer Points Now, Figure It Out Later" Is Bad Advice for JAL
I would push back hard on the idea of speculatively transferring credit card points into JMB. Programs like Bilt, Capital One, and Marriott Bonvoy let you move points into JAL, and a lot of travel blogs encourage stockpiling.
But the 36-month hard expiration makes JAL one of the worst programs to park points in without a booking plan. The cancellation/rebooking fee is only about 3,100 yen (roughly $21), so if award availability disappears, rebooking is cheap.
The safe play: open your JMB account now, but do not transfer points until you have a specific flight in mind and have confirmed award availability.
Two Exceptions That Pause the Expiration Clock
JAL does offer relief for its highest-tier members:
- JMB Diamond members get their mileage expiration fully suspended for the duration of their Diamond status
- JMB Elite members get a 60-month validity window instead of 36, but only for miles earned from January 2025 onward
- JAL Global Club (JGC) lifetime members retain some protections, though the specifics vary by region
For a first-time JMB enrollee, none of these apply. Plan around the 36-month window.
JAL USA Card: Worth the $35 or Not?
The JAL USA Card is a co-branded Mastercard issued by FNBO. The Basic Rewards tier charges a $35 annual fee and earns 1 mile per $1 spent on all purchases.
The Premium Rewards tier costs $85 total ($35 annual fee plus a $50 upgrade fee) and earns 2 miles per $1 on eligible JAL purchases, plus 1 mile per $1 on everything else.
| Feature | Basic Rewards | Premium Rewards |
|---|---|---|
| Annual fee | $35 | $85 |
| Earn rate (JAL purchases) | 1 mile per $1 | 2 miles per $1 |
| Earn rate (other purchases) | 1 mile per $1 | 1 mile per $1 |
| First international flight bonus | Yes (one-time) | Yes (one-time) |
| In-flight purchase discount | Limited | Included |
My take on the Premium tier: it only makes sense if you spend more than $1,000 per year directly on JAL tickets. Below that threshold, the extra $50 fee earns back fewer miles than the fee costs.
Who Can You Book Award Flights For?
JAL is strict on this. Award tickets can only be booked for yourself and family members related by blood or marriage, up to two degrees.
A friend, a partner you are not married to, or a cousin does not qualify.
This catches people off guard because most US-based programs let you book awards for anyone. JAL requires you to register eligible family members in your JMB account before booking.
Three things to verify on the official JAL site before you try to book for someone else:
- The family member's name must match their passport exactly
- Registration can take a few business days to process
- JAL may request documentation to verify the relationship
Keeping Your JMB Account Secure
Travel loyalty accounts are frequent targets for fraud. The JAL Mileage Bank app added login alert emails as of July 2025, which notify you any time someone accesses your account.
A few steps worth taking right after enrollment:
- Set a password unique to your JMB account (do not reuse passwords from other sites)
- Enable two-step authentication if available in your region
- Check your mileage balance periodically for unfamiliar activity, especially after using public Wi-Fi abroad
If something looks off, contact JAL support immediately. A stolen mileage balance cannot be reinstated once the miles are redeemed by someone else.
Questions People Ask About JAL Mileage Bank Cards
These come up constantly in travel forums and search results. Quick answers in plain language.
- Q: Is JAL Mileage Bank free to join?
There is no registration fee and no annual membership fee for a standard JMB account. The only costs come if you add a co-branded credit card like the JAL USA Card, which starts at $35 per year. - Q: Can I extend my JAL miles before they expire?
No. JAL does not offer any extension, reinstatement, or activity-based reset for expired miles. The only exceptions are for JMB Diamond members (expiration paused) and JMB Elite members (60-month window for miles earned from January 2025 onward). - Q: Do I still get a physical membership card?
JAL stopped issuing physical JMB cards on August 4, 2025. New members receive a digital membership through the JAL Mileage Bank app. Existing physical cards still function, but replacements are no longer available.
Conclusion
The JAL Mileage Bank application is the easy part of this whole process. The expiration policy, the family-only booking restriction, and the regional portal differences are where people lose time and miles.
Sign up through the correct regional JAL site, keep your passport name consistent across every form, skip the speculative point transfers, and set a calendar reminder 30 days before your oldest miles expire.
That last step alone will save more value than any credit card signup bonus.
