Booking a trip with Miles alone

Written by Miles (SI), Director, Loyalty & Rewards · Updated 2026-10-05

If your Defera Miles balance covers a trip's full total, you can book the whole trip with Miles. Look for Book with Miles on the review page at checkout. There's no card to add and no payment plan.

Because there's nothing left to pay, our team releases your confirmation number the same way it does for any trip that's paid in full. Your confirmation number is the code the airline uses to find your reservation.

How does it work?

Here's what happens:

  1. Choose your trip. Search and pick your flights, then continue to checkout as usual.
  2. Tap Book with Miles. You'll see it on the review page when your Miles balance covers the trip's full total.
  3. Your trip is booked. It's paid with Miles alone, so there's no card to charge and no payment schedule.
  4. Our team releases your confirmation number. It appears on your trip page in Trips.

To see how long the release takes, read When do I get my confirmation number?

How many Miles do I need?

Enough to cover the trip's full total, at 1.25¢ a Mile. To see what your balance is worth, use the Miles Value Calculator on the Rewards page.

If your Miles cover only part of a trip, you can still use them at checkout to lower the price. In that case, at least $25 stays on your payment plan.

When isn't it offered?

Book with Miles isn't offered on:

  • Flight + Hotel packages. You can use Miles on a package, but it can't be booked with Miles alone, so part of it always stays on the payment plan.
  • Trips with an airline travel credit applied. That's a credit from an airline that you add at checkout.

If your balance covers the whole trip and you don't see Book with Miles, ask the Defera Concierge, our AI concierge.

Do I earn Miles on this trip?

No. Miles are earned on what you pay in money, not on the part your Miles covered. A trip booked with Miles alone doesn't earn new Miles.

What if I need to cancel?

A trip paid entirely with Miles is cancelled through our team. Here's how:

  1. Open the trip. Go to Trips and tap the trip.
  2. Open Flight Options and tap Cancel. A chat with the Defera Concierge opens, and it sends your request to our team.
  3. Your Miles come back. When the trip is cancelled, your Miles return to your account automatically.
