Capital One Added JAL: 30% Bonus Ends Sept. 30

Capital One added Japan Airlines Mileage Bank and Qatar Airways Privilege Club as transfer partners in September 2025 — JAL transfers at 2:1.5 (4:3) and Qatar Airways at 1:1. A 30% JAL transfer bonus (1,000:975, close to 1:1) runs through September 30, 2026. Verify the partner and award in your own account before moving miles.

Travel Points MathReviewed September 22, 202610 min read

Capital One added Japan Airlines Mileage Bank and Qatar Airways Privilege Club as transfer partners in September 2025, alongside I Prefer Hotel Rewards. Japan Airlines transfers at 2:1.5 — the same ratio as 4:3, or 750 JAL miles per 1,000 Capital One miles. Qatar Airways transfers at 1:1. The reason to look at this now: Capital One is running a 30% transfer bonus to Japan Airlines Mileage Bank, reported to run from September 1 through September 30, 2026, which pushes the effective ratio to roughly 1,000:975 — close to 1:1. The bonus is a reason to look at the math, not a reason to transfer by itself; you still need a specific, bookable JAL award before moving miles.

This page does not claim live JAL or Qatar Airways award availability or pricing. Confirm the current partner, ratio, and any bonus in your own logged-in Capital One account before transferring.

The short answer

Question Answer
Are JAL and Qatar Airways really new Capital One partners? They were added in September 2025, so they are established, not brand-new this week — the current news is the bonus, not the partnership itself.
What is the JAL transfer ratio? 2:1.5, equivalent to 4:3 — 750 JAL miles per 1,000 Capital One miles transferred, without a bonus.
What is the Qatar Airways transfer ratio? 1:1.
What is the current bonus? A reported 30% transfer bonus to JAL Mileage Bank, making the effective ratio about 1,000:975.
When does the bonus end? Reported through September 30, 2026.
Is this the first time this bonus has run? No — reporting describes this as roughly the fourth time Capital One has run a JAL transfer bonus since the partnership launched in September 2025.

What actually changed, and when

It is worth separating two different facts that both show up under "Capital One added Japan Airlines and Qatar Airways":

  1. The partnership itself is not new. Capital One added Japan Airlines Mileage Bank, Qatar Airways Privilege Club, and I Prefer Hotel Rewards as transfer partners starting September 23, 2025, bringing Capital One's total transfer partner count to 22 — more than any other major bank transfer program, per the reporting cited here.
  2. The bonus is the timely part. Capital One has run a 30% JAL transfer bonus multiple times since that launch — reporting points to previous rounds around the partnership's September 2025 launch, February 2026, and April 2026 — and a new round is reported live from September 1 through September 30, 2026.

If your search brought you here expecting brand-new partners, the accurate framing is: the partners have existed for about a year, and what is genuinely time-sensitive right now is this specific bonus window.

Worked math: the bonus math on the JAL ratio

JAL's base transfer ratio is not 1:1, so the math needs the base ratio before applying the bonus — the same pattern this site uses for other non-1:1 partners:

Capital One miles needed (no bonus) = JAL award price ÷ 0.75
Capital One miles needed (with 30% bonus) = JAL award price ÷ (0.75 x 1.30)

Illustrative numbers only, using the confirmed base ratio and reported bonus — not a live JAL award price:

JAL award price (JAL miles) Capital One miles needed, no bonus Capital One miles needed, with 30% bonus (through Sept. 30) Capital One miles saved
25,000 33,333 25,641 7,692
50,000 66,667 51,282 15,385
85,000 113,333 87,179 26,154

The pattern holds at every size: the 30% bonus turns a 2:1.5 ratio (25% worse than 1:1) into something close to 1:1 — a meaningful discount, but only worth using against an award you can actually book.

Our free transfer bonus calculator applies the 1:1 version of this formula directly; for JAL's 0.75 base ratio, convert the JAL award price to "Capital One-equivalent" first as shown above, then run the bonus. To see what the same Capital One balance is worth as cash back or through Capital One Travel instead, our free Capital One miles to dollars calculator compares all three side by side.

What to check before you transfer

  • Confirm JAL shows as a transfer partner in your own Capital One account. A general partner list is not the same as the option appearing for your specific account and card.
  • Confirm which Capital One cards you hold actually earn transferable miles. Miles-earning cards such as Venture and Venture X are the ones reporting ties to this bonus; a cash-back-only card (Quicksilver, Savor) does not transfer miles on its own unless paired with a miles-earning account.
  • Open or verify your JAL Mileage Bank account before transferring. Reporting describes Capital One negotiating an exception to JAL's normal new-account waiting period so transferred miles can be redeemed sooner — but this is a detail to confirm at the time of transfer, not something this page can guarantee still applies.
  • Check JAL's mileage expiration and redemption rules. Reporting describes a hard, multi-year expiration on JAL miles with no extensions, and redemption rules that can be narrower than a typical airline program (for example, restrictions on who an award ticket can be booked for). Verify current rules directly with JAL Mileage Bank before transferring.
  • Have the exact JAL award found and priced, in JAL miles, in the JAL Mileage Bank booking tool itself — not a third-party estimate.

Our own Capital One-to-JAL transfer page and Capital One-to-Qatar-Airways transfer page track the base ratio, minimums, and source verified directly against Capital One's own partner page — useful for confirming the no-bonus baseline before you apply the September math above.

Go/no-go checklist tied to the September 30 deadline

  • I hold a Capital One card that earns transferable miles (for example Venture or Venture X), not only a cash-back-only card.
  • Japan Airlines Mileage Bank currently shows as a transfer partner in my own logged-in Capital One account.
  • I have a specific JAL award — route, date, cabin — found and priced directly in JAL Mileage Bank.
  • I ran the bonus math above (or the transfer bonus calculator) and the discounted Capital One-miles cost beats what I would pay in cash or through another program.
  • I have a JAL Mileage Bank account open and ready, with the traveler's name matching exactly.
  • I understand JAL miles expire and that this transfer is one-way — I am not moving miles "just in case."
  • I can complete the transfer before September 30, 2026, not just decide by that date.

If every box is checked, the bonus window is a real reason to act now. If any box is unchecked — especially "I have a specific JAL award found and priced" — wait. A 30% discount on miles you cannot use is not a deal.

When to skip the bonus and wait

  • You do not have a JAL award found and priced yet, and you are not going to find one before September 30.
  • Qatar Airways or another 1:1 partner better matches the trip you actually want, and chasing the JAL discount would mean booking a worse itinerary just for the bonus.
  • You are unsure your card earns transferable Capital One miles at all.
  • Reporting describes this as roughly the fourth time this specific bonus has run since September 2025 — if you miss this window, the pattern suggests another one is plausible, though this page cannot promise Capital One will repeat it again.

If you have not yet confirmed the general rules for moving Capital One miles to any airline — not just JAL — the Capital One transfer-safety guide covers the broader no-stranding checklist this page assumes you already know. If the reason you are moving fast is a deadline in general rather than this specific JAL bonus, the transfer-before-the-bonus-ends guide walks through how to separate genuine urgency from a deadline that does not actually change your decision. And if you are weighing a Chase-side deadline at the same time, the Chase-to-Hyatt ratio guide runs the same kind of before/after math for a different program with its own October 1, 2026 cutoff.

FAQ

Did Capital One really add Japan Airlines and Qatar Airways as transfer partners?

Yes, but not this week. Reporting places the launch of Japan Airlines Mileage Bank, Qatar Airways Privilege Club, and I Prefer Hotel Rewards as Capital One transfer partners on September 23, 2025. What is new right now is a reported 30% transfer bonus to JAL running through September 30, 2026.

What is the Capital One-to-JAL transfer ratio?

Reporting describes a 2:1.5 ratio, the same as 4:3 — 750 JAL miles for every 1,000 Capital One miles transferred, before any bonus.

What is the Capital One-to-Qatar Airways transfer ratio?

Reporting describes a 1:1 ratio for Qatar Airways Privilege Club.

How much is the current JAL transfer bonus, and when does it end?

Reporting describes a 30% bonus, making the effective ratio roughly 1,000 Capital One miles to 975 JAL miles, reported to run through September 30, 2026. Confirm the current offer and exact end date in your own account before transferring, since promotions can end early.

Should I transfer Capital One miles to JAL just because the bonus is ending soon?

No, not by itself. Only transfer if you already have a specific JAL award found and priced that clears your baseline once the bonus is applied. Transfers to JAL are one-way, and JAL miles carry their own expiration and redemption rules.

Transfer partner decision walkthroughs

Can You Transfer Capital One Miles to Airlines?

Yes, some eligible Capital One travel rewards miles can be transferred to select airline and hotel loyalty programs. Capital One’s own transfer-partner guide says cardholders can transfer rewards miles to Capital One travel partner loyalty programs, and its Venture and Venture X pages describe transfer access to 15+ travel loyalty programs. Do not treat that as permission to transfer blindly: verify your exact card/account eligibility, the partner in your logged-in Capital One account, the award you plan to book, and any terms shown before moving miles.

Transfer Before the Bonus Ends, or Wait? Do the Math

Transfer before a bonus ends only if you already have a specific redemption that beats your baseline value once the bonus is applied — a deadline is not a reason by itself. Two real September 2026 bonuses (Amex to British Airways Avios at 30% through September 27, and Citi ThankYou to Leaders Club at 25% through September 19) show how deadline pressure and actual value are separate questions.
