Can You Really Use Someone Else’s Airline Miles?

Yes, absolutely.

In fact, booking a flight for a friend or family member is one of the best ways to use your hard-earned miles.

However, there is a massive difference between using miles for someone and transferring miles to them. One is free; the other is a "money pit" that can cost you hundreds of dollars in fees.

  • The Smart Way: You log into your account and book a ticket in their name. (Cost: $0)
  • The Expensive Way: You transfer your miles to their account so they can book it. (Cost: $$$)

This guide explains how to book tickets for others on major airlines (United, Delta, American), how to use new "Family Pooling" features, and why you should almost never pay to transfer points.


Method 1: The "Booking" Strategy (Best & Free)

This is the method 99% of people should use. You do not need to be related to the passenger to do this.

How it works:

  1. Log in to your own frequent flyer account (e.g., United MileagePlus).
  2. Search for the flight just like you would for yourself.
  3. Select the flight and proceed to checkout.
  4. Enter the Passenger's Info: Instead of your name, type in the name, date of birth, and gender of the person flying.
  5. Enter Your Payment Info: Pay the small taxes and fees (usually $5.60 for domestic US flights) with your credit card.

The Result: The ticket is issued in their name, but paid for with your miles. They get the boarding pass, and you get to be the hero.

Crucial Warning: Do NOT put your Frequent Flyer number on their ticket. Frequent flyer numbers must match the name of the traveler. If you enter your number on their ticket, the system will likely reject it or remove your elite benefits.


Method 2: Family Pooling (New & Free)

In 2024 and 2025, several major airlines introduced "Pooling," allowing groups to combine miles for free. This is the only time "transferring" miles makes sense.

United Airlines Pooling

United now allows up to 5 members to join a "pool."

  • How it works: A "Pool Leader" creates the group. Members contribute miles to the pool for free.
  • The Catch: Pooled miles can only be used for flights on United and United Express (not partner airlines like Lufthansa).
  • Who is it for? Perfect for families who want to combine small balances to buy one big ticket.

JetBlue Points Pooling

JetBlue allows up to 7 members (friends or family) to pool points.

  • Pros: It is completely free and allows you to reach award thresholds faster.
  • Cons: The "Pool Leader" controls the points, so only pool with people you trust!

Frontier Airlines

Frontier allows pooling, but usually only if the lead member has elite status or the specific Frontier credit card.


Method 3: Transferring Miles (Avoid This!)

Most airlines (Delta, United, AA) will happily let you "transfer" miles from your account to another person's account. You should almost never do this.

Airlines charge massive transaction fees that ruin the value of the miles.

The Cost of Transferring (Examples):

  • Delta: $0.01 per mile + $30 fee. (Transferring 30,000 miles costs $330!)
  • United: $0.015 per mile + $30 fee. (Transferring 30,000 miles costs $480!)
  • American: ~$0.005 per mile. (Cheaper, but still unnecessary).

Why is it so expensive? Airlines want to prevent a "black market" of people selling miles to strangers. The high fees make buying a cash ticket cheaper than transferring miles in most cases.

The Only Exception: If you are short by a tiny amount (e.g., you have 58,000 miles but need 60,000 for a flight), paying $20 to transfer 2,000 miles from a spouse might be worth it to unlock the ticket.

FAQ: Using Miles for Others

Q: Can I use my frequent flyer number for someone else?A: No. You cannot earn miles on a flight you aren't flying. If you put your number on a ticket for "John Smith," the airline's system will flag the mismatch. John should use his own number to earn miles on the flight (yes, even on an award ticket, some airlines now award status credits!).

Q: Does the credit card holder have to be the passenger?A: No. You can pay the taxes and fees ($5.60) with your credit card, even if the ticket is for someone else.

Q: Can I transfer Capital One/Chase/Amex points to my friend?A: Usually No.

  • Chase: You can only transfer points to a spouse/partner living at the same address.
  • Amex: You can generally only transfer to your own airline loyalty account.
  • Workaround: Transfer the points to your airline account (e.g., your British Airways account) and then book the ticket for your friend from there.

Q: What happens if I cancel the ticket?A: If you book a ticket for a friend using your miles and need to cancel, the miles will typically go back into your account, not theirs. However, any flight credits for taxes/fees might be issued in the passenger's name.
