Can You Transfer Airline Miles to Another Airline?

• Stays put

  Miles stay in the issuing program rather than moving between airlines

• Partner redemption

  A partnership lets you spend miles on a partner flight, not move the balance

• Fee-based

  A transfer to another person in the same program can cost money

• Check the program

  American and Delta each publish their own transfer and partner terms

“Can I transfer my miles to another airline?” is one of those questions where the intuitive answer and the real answer diverge. The intuitive answer is that miles are like money you can move. The real answer is that airline miles generally stay in the issuing program, and you cannot move them into another airline’s account the way you might move cash between banks. Partnerships change what you can spend them on, not where they live.

The distinction between a transfer and a redemption is the entire lesson of this page. A partnership lets a member redeem their issuing program’s miles for an eligible partner flight — that is spending the miles where they are. A transfer would move the balance itself, and that is the thing airline programs do not generally offer across airlines. American and Delta each publish their own program rules that make this separation explicit.

A note on scope. This is about moving existing airline miles, not about how many points you need or whether points beat cash. The using miles for someone else guide covers the same-program case, and the points-pooling guide covers combining balances within a household. Here the question is moving miles across airlines.

The short answer

Airline miles generally stay in the issuing program. A partnership lets you redeem those miles for an eligible partner flight, which is not the same as transferring the balance into the partner’s own program. A transfer to another person in the same program is a different, often fee-based case. Every program publishes its own terms, so confirm the current rule before you act.

Miles stay in the issuing program

The starting fact is that miles are issued, tracked and redeemed within a single program. Your AAdvantage miles live in your AAdvantage account; your SkyMiles live in your SkyMiles account. That balance does not migrate to another airline on its own, and no standing mechanism moves it on request. The program that issued the miles is the program that administers them.

American’s AAdvantage terms, Delta’s SkyMiles rules and the programs that mirror them all frame miles as program-specific balances. This is why a search for “transfer miles between airlines” surfaces more questions than rules: the thing people want — a direct cross-program move — is generally not how airline programs are built. The design is program-locked by default.

Partnerships are redemptions, not transfers

The main way to use miles on another airline is a partner redemption, not a transfer. American publishes the partner airlines on which you can spend AAdvantage miles, and Delta publishes the SkyMiles airline partners and the routes they open, and in each case you are spending your miles in your program on a seat a partner operates. The miles never leave your account.

This is a real and useful ability, and it is why most people think miles are transferable. But the distinction matters for planning: a partner redemption is bound by your issuing program’s award and change rules, and it does not give the partner a balance of your miles to use however it likes. You get a partner flight; you do not get a transfer.

A transfer to another person is different

A transfer to another person in the same program is a separate case from moving miles between airlines. American’s gift-and-transfer help describes how AAdvantage miles can be moved to another member, and the move can carry a fee and be subject to minimum or maximum limits. This is a transfer, but within a program, not across programs.

The practical implication is that you cannot solve a cross-airline gap by gifting your miles, because a gift stays in the same program. If the person who needs miles belongs to a different airline, the gift cannot cross over. The using miles for someone else guide walks through the options that do work within a program.

Why miles are not like a bank balance

Miles are not like a bank balance you can wire. A bank account is a fungible amount of currency that moves between institutions; an airline mile is a record inside a loyalty program with the program’s own earning, redemption and expiration rules. That structural difference is why you cannot simply move miles to another airline the way you move money to another bank.

It also shapes how you plan. Because miles are program-locked, the useful question is not “how do I move them” but “what can this program’s miles buy, here and with partners, before they expire?” The do miles expire guide helps you value the balance in its own program rather than looking for a way to relocate it.

Bank and hotel points are a separate case

Converting credit-card or hotel points into an airline program is a different mechanism and it is not a workaround for transferring airline miles. When an issuer converts points to an airline, the points are bought or transferred into that specific program at the issuer’s own partners and ratios. It does not move an existing airline balance into another airline, and it is not a general path around the transfer limit.

It is worth keeping the categories separate because they answer different plans. A points conversion brings a new balance into one program; an airline-to-airline transfer would move an existing balance. If your goal is to use an existing airline balance on a partner, the redemption path, not a conversion, is what applies. Read the issuer’s current partners and the program’s terms for the exact action.

Where fees and limits apply

Where a transfer is allowed at all, it commonly carries a fee plus possible limits on amount and frequency. American and Delta each publish their own terms, and what applies to a same-program gift or transfer differs from a redemption on a partner. The fee and the limits are the program’s, so confirm them on the issuing page before you transfer rather than assuming a universal cost.

Because the fee is program-specific, it is also part of the value decision. A transfer that carries a fee only makes sense if the miles you are moving are worth more than the fee. The how many points you need guide and the transfer-partners guide help you price the value so a fee-laden move does not quietly lose you more than the miles are worth.

How to proceed when you want cross-airline use

When you want to use miles across airlines, follow the redemption path rather than looking for a transfer. Choose the partner airline on which you want to fly, check that it is an eligible partner in your issuing program, read the program’s award and partner-flight terms, and book through your program’s flow using your own miles. American and Delta each document their partner airlines and how to redeem on them.

If instead you need miles in another person’s same-program account, use that program’s gift-and-transfer feature and read its fee before you move. And if you want to grow a balance for a partner, a points conversion into that specific program is the available mechanism, not a cross-airline move. Match the tool to the actual action and the current program terms decide the rest.

Transfer versus redemption at a glance

The table keeps the three cases distinct so you can pick the right one. Only the gift moves a balance, and it stays within one program; the partner redemption is a spend, not a move; and a true cross-airline transfer is not generally on offer. Match your goal to the row, then read the program’s current terms.

Airline miles generally stay in the issuing program, and partnerships let you redeem them for eligible partner flights rather than moving the balance into another airline. A transfer to another person in the same program is a different, often fee-based case, and converting bank or hotel points is a separate mechanism. Read the issuing program’s current partner and transfer terms before you act, and use the redemption or gift path it documents rather than chasing a cross-airline move that is not generally offered.
