Japan Airlines' Mileage Bank is their frequent flyer program, and you can join it free online in minutes

Japan Airlines (JAL) runs a frequent flyer program called Mileage Bank. You create an account on their website, provide your name and email, and start earning miles on flights and partner purchases when ready. There is no membership fee, no annual cost, and no spending requirement to keep the account active. Miles accumulate on every JAL flight and on purchases through their partner network, and you can redeem them for flights, seat upgrades, or partner rewards.

The program works whether you book through JAL directly, through a travel agent, or through a third-party booking site — as long as you enter your Mileage Bank number at booking. If you forget to add it before you fly, you can request miles to be added within a set window after your flight, though the process is slower than having the number in the reservation from the start.

Key Takeaways

  • Mileage Bank membership is free and takes about five minutes to set up on JAL's website with just your name, email, and a password.
  • You earn miles on every JAL flight and on purchases from partner merchants, hotels, and credit card spending if you hold a JAL co-branded card.
  • Miles do not expire as long as you earn or redeem at least one mile every 36 months, so occasional flyers can keep balances indefinitely.
  • You can redeem miles for domestic and international flights, seat upgrades, or partner rewards like hotel nights and car rentals.

How to create your Mileage Bank account

Go to the JAL Mileage Bank website and select the option to create a new member account. You will need a valid email address, your full name as it appears on your passport or ID, your date of birth, and a password. JAL will send a confirmation email to the address you provide — click the link in that email to set up your account.

Once your account is active, you receive a Mileage Bank number when ready. Write this number down or save it in your phone. You will need it every time you book a JAL flight to may support miles post to your account. If you already have a JAL account from a previous booking, you can link that booking history to your new Mileage Bank account by providing the booking reference and your name.

Earning miles on flights and everyday purchases

Every JAL flight earns miles based on the distance flown and the cabin class you booked. Economy flights earn fewer miles per mile flown than business or first class. Domestic flights within Japan typically earn between 500 and 2,000 miles depending on distance, while international long-haul flights can earn 5,000 to 15,000 miles or more. The exact amount depends on the route, the fare class you purchased, and any promotions JAL is running that month.

You also earn miles through JAL's partner network without flying. Partner hotels, car rental companies, and shopping portals award miles on bookings and purchases. If you hold a JAL co-branded credit card, you earn miles on every dollar you spend with that card — typically one mile per dollar, though some cards offer bonus earning rates on certain categories. Partner airlines in the oneworld alliance also allow you to earn JAL miles when you fly with them, though the earning rate varies by airline and ticket type.

How miles expire and how to keep your account active

JAL miles do not expire if you earn or redeem at least one mile within any 36-month period. This means if you fly once every three years, or make one partner purchase every three years, your entire balance stays active indefinitely. If your account goes 36 months with no activity, JAL will close it and you will lose any remaining miles.

The 36-month clock resets every time you earn or redeem, so even a small purchase through a partner merchant or a single domestic flight is enough to keep your account alive. If you are not a frequent flyer, setting a calendar reminder to make one small purchase or book one flight every two years is a straightforward way to preserve your balance.

Redeeming miles for flights and upgrades

The most common use of JAL miles is booking flights. Domestic flights in Japan typically cost between 5,000 and 40,000 miles depending on the route and how far in advance you book. International flights range from 30,000 miles for short regional routes to 100,000 or more miles for premium cabin seats on long-haul flights. JAL publishes award charts on their website showing the mile cost for each route and cabin class.

You can also use miles to upgrade an existing ticket from economy to business or first class, though the upgrade cost is usually separate from the base award price. Partner airlines in the oneworld alliance also allow you to book flights using JAL miles, which can be useful if JAL does not fly a route you need. Redemption options and availability vary by season and route, so checking the JAL website directly is the fastest way to see what is available for your travel dates.

Partner rewards beyond flights

JAL miles can be redeemed for more than flights. Partner hotels allow you to book nights using miles, typically at rates between 5,000 and 50,000 miles per night depending on the property and location. Car rental companies, travel insurance, and shopping vouchers are also available. Some partners allow you to transfer miles at a fixed rate, while others let you book directly through the JAL website and deduct miles from your account.

The value you get from non-flight redemptions varies widely. A hotel night booked with miles might represent better or worse value than using those same miles for a flight, depending on the property, the season, and current flight award prices. Comparing the mile cost to what you would pay in cash helps you decide whether a particular redemption is worth it.

Frequently Asked Questions

Do I need a credit card to join Mileage Bank?

No. The Mileage Bank membership itself is free and requires no credit card. You earn miles on flights and partner purchases using just your membership number. A JAL co-branded credit card accelerates earning, but it is optional.

Can I combine miles with a family member or transfer miles to someone else?

JAL does not allow direct transfers between members. However, some partner programs and redemption options may allow you to book travel for another person using your miles. Check the specific redemption terms on the JAL website for the option you are considering.

What happens if I book through a third-party site like Expedia or Kayak?

You can still earn miles if you enter your Mileage Bank number in the booking. However, some third-party sites do not display the Mileage Bank field, so miles may not post automatically. If that happens, contact JAL customer service with your booking reference and they can add the miles manually within a set timeframe.

How long does it take to see miles in my account after a flight?

Miles typically post within a few days of your flight. If you do not see them within a week, contact JAL with your booking reference and they will investigate. Miles from partner purchases may take longer, depending on the partner's reporting schedule.

Can I use miles to book a flight for someone else?

Yes. You can redeem your miles to book a flight for another person, though the ticket will be issued in their name. The person flying does not need to be a Mileage Bank member, but you will need their full name and date of birth to complete the booking.
