What American Express transfer bonuses are and how they work
American Express transfer bonuses let you convert credit card points into airline miles or hotel nights at a rate better than the standard conversion. Instead of trading points one-to-one, you might get 1.25 or 1.5 miles per point during a promotional period. The bonus applies to points you transfer during the offer window — usually 30 to 90 days — and Amex announces these offers through email to cardholders and on their website.
The mechanics are straightforward: you log into your Amex account, select a transfer partner (such as Delta, United, or Marriott Bonvoy), choose how many points to move, and the bonus multiplier applies automatically at the time of transfer. The miles or nights land in your partner account within one to three business days. You do not need to do anything special to "set up" the bonus — it works on every transfer you make during the promotional period.
Transfer bonuses matter because they can add 25 to 50 percent more value to points you already have. If you were planning to transfer 50,000 points to an airline anyway, a 1.25x bonus gives you 62,500 miles instead. That difference can cover an extra domestic flight or push you closer to a premium cabin upgrade.
Key Takeaways
- Transfer bonuses multiply your points at the time you transfer them, typically offering 1.25x to 1.5x the standard rate for 30 to 90 days.
- Amex announces bonuses through cardmember email and their website, and the bonus applies automatically when you transfer during the offer period.
- Different cards and transfer partners have different bonus schedules — a bonus on Delta transfers does not mean Marriott transfers are also boosted.
- Bonuses change several times per year, so the rate available today may not be available next month.
- You should transfer points only if you have a specific trip or redemption in mind, because points held in airline accounts can expire or lose value.
How often Amex changes transfer bonuses
Amex does not publish a fixed schedule for when bonuses change. Instead, they rotate offers throughout the year based on their business goals and partnership agreements with airlines and hotels. Some transfer partners see bonuses multiple times per year; others may go months without a promotional offer.
The pattern is not random, but it is not predictable either. Historically, bonuses tend to appear more frequently during travel-heavy seasons (spring and summer) and around major shopping periods (back-to-school, holiday). But Amex has run bonuses in off-season months as well, and the timing varies by partner.
If you are tracking a specific airline or hotel program, the most reliable way to stay informed is to check your Amex account regularly or sign up for Amex's promotional email list. Third-party credit card websites and blogs also track bonus announcements, though these sources are not affiliated with Amex and may not catch every offer when ready.
Which cards and transfer partners have bonuses right now
Transfer bonuses are card-specific and partner-specific. Your American Express Gold Card might have a bonus on Marriott transfers while your Platinum Card has a bonus on United transfers. A bonus on one card does not carry over to another, even if both cards can transfer to the same partner.
The current offers change frequently and vary based on your account status and card history. The most direct way to see what bonuses you have access to is to log into your Amex account and navigate to the Membership Rewards transfer section. Amex will display any active bonuses for your specific cards and partners.
If you do not see a bonus for a partner you want to transfer to, you have two options: wait for a future bonus to appear, or transfer at the standard 1:1 rate. There is no penalty for waiting, and bonuses do return — the question is whether your travel timeline allows you to wait.
The difference between transfer bonuses and points-earning bonuses
Transfer bonuses and points-earning bonuses are separate things and should not be confused. A points-earning bonus is a sign-up offer or category bonus that gives you extra points when you spend money — for example, "earn 75,000 bonus points after you spend $5,000 in the first three months." A transfer bonus multiplies points you already have when you move them to a partner.
Both can improve the value of your rewards, but they work at different times. You earn the points first (with or without a bonus), then later you transfer them (with or without a transfer bonus). If you have a large points balance and a transfer bonus appears, you can move those points at the better rate regardless of when or how you earned them.
When to transfer points during a bonus versus waiting
The decision to transfer during a bonus depends on whether you have a specific redemption in mind. If you know you are booking a trip in the next two months and you need miles to cover it, transfer during a bonus if one is available. The extra miles can make the difference between paying cash for a flight and redeeming miles.
If you do not have a trip planned, holding points in your Amex account is usually safer than transferring them to an airline account. Amex Membership Rewards points do not expire as long as your account remains open and active. Airline miles, by contrast, can expire if you do not use them within a set period (typically three to five years, depending on the airline) or if your frequent flyer account closes.
The risk of waiting for a bonus is that the bonus may not return soon, or it may return at a lower rate. But the risk of transferring without a redemption plan is that you lock your points into an airline account where they may expire or become harder to use. For most people, having a specific trip or redemption goal is the right trigger to transfer.
How transfer bonuses compare across different card issuers
American Express is not the only card issuer that offers transfer bonuses. Chase Sapphire cards, Citi Prestige, and other premium cards also run transfer bonuses to their partner networks. The rates, frequency, and partner lists differ by issuer.
Amex's transfer partners include most major airlines (Delta, United, American, Southwest, JetBlue, Alaska) and hotel chains (Marriott Bonvoy, Hilton Honors, IHG One Rewards). Chase's partners overlap in some cases but differ in others. If you hold cards from multiple issuers, you may see different bonuses available across your accounts, which can help you choose which points to transfer first.
Comparing bonuses across issuers makes sense only if you actually hold multiple cards. If you have only Amex cards, your choice is whether to transfer now at the current bonus or wait for a future bonus. If you have both Amex and Chase cards, you can compare the bonuses available to each and transfer from whichever account offers the better rate.
What to do if you miss a transfer bonus
If a bonus expires before you transfer, you have missed that particular offer, but you have not lost anything. Your points remain in your Amex account at their full value. You can transfer them at the standard 1:1 rate, or you can wait for the next bonus to appear on that partner.
The cost of missing a bonus is the difference between what you would have received with the bonus and what you receive without it. If you had 50,000 points and a 1.25x bonus expired, you gave up 12,500 miles by not transferring during the offer window. That is a real opportunity cost, but it does not prevent you from transferring later.
To avoid missing bonuses in the future, check your Amex account before you plan a trip. If a bonus is active and you know you will need miles, transfer when ready rather than waiting. Bonuses can end early if Amex decides to close them, and there is no way to predict when that will happen.
Frequently Asked Questions
Do I have to use the transfer bonus if it is available?
No. The bonus applies only to transfers you make during the offer period. If you do not transfer, the bonus expires and you keep your points. You can transfer later at the standard rate, or wait for a future bonus.
Can I transfer points to multiple partners during the same bonus period?
Yes. If Amex is running bonuses on both Delta and United at the same time, you can transfer some points to Delta and some to United, and both transfers will receive their respective bonuses. Each partner has its own bonus offer.
What happens to my points if I transfer them during a bonus and then do not use the miles?
Once points are transferred to an airline account, they become miles in that airline's program and are subject to that airline's expiration rules. Most airlines expire miles after three to five years of inactivity. Amex does not manage them anymore, so you need to track the airline's policy.
Are transfer bonuses the same for all cardholders?
Mostly, but not always. Amex sometimes runs targeted bonuses that appear only to certain cardholders based on account history or spending patterns. The bonuses visible in your account are the ones you can use. If you do not see a bonus, it may not be available to you at that time.
How do I know when a new transfer bonus is coming?
Check your Amex account regularly or sign up for Amex promotional emails. Credit card blogs and reward tracking websites also publish bonus announcements, though these are not official Amex sources. There is no way to predict bonuses in advance — they are announced when Amex decides to run them.
