Booking a flight doesn't have to mean wiping out your bank account in one shot. Buy now pay later (BNPL) apps have changed the game — letting travelers fly now and spread the cost over weeks or months, often with 0% interest options.

But not all BNPL apps work equally well for flights. Some have higher limits, better airline coverage, or more flexible repayment terms. Here's our breakdown of the best options in 2025.

What is Buy Now Pay Later for Flights?

BNPL services let you split a purchase into multiple installments — typically 4 payments over 6 weeks (interest-free) or monthly installments over 3–36 months (with or without interest depending on your credit).

For flights, this means you can:

• ▸Book seats months in advance while paying over time
• ▸Secure better prices early without having full funds upfront
• ▸Manage cash flow for expensive international flights

Top BNPL Apps for Booking Flights

1. Affirm

Affirm is the most widely accepted BNPL service for travel. It offers:

• ▸0% APR promotional offers on select purchases
• ▸Loan amounts from $50 to $30,000
• ▸Repayment terms from 1–48 months
• ▸No late fees

Affirm works with hundreds of travel partners and can be used at checkout on many major booking platforms.

2. Klarna

Klarna offers three ways to pay:

• ▸Pay in 4 — 4 interest-free payments every 2 weeks
• ▸Pay in 30 — buy now, pay 30 days later
• ▸Financing — monthly payments up to 36 months

Klarna's virtual card feature (One-time card) lets you use it almost anywhere that accepts Visa.

3. Afterpay

Afterpay's model is simple: 4 payments, every 2 weeks, always 0% interest. The tradeoff is a lower spending limit (typically up to $2,000), which works for domestic flights but may fall short for premium international tickets.

4. Sezzle

Sezzle works similarly to Afterpay — 4 installments over 6 weeks. Its Sezzle Up program lets you build credit while paying, which is a nice bonus for frequent travelers.

5. Zip (formerly Quadpay)

Zip splits your purchase into 4 payments over 6 weeks and charges a small flat fee per installment rather than interest. It's transparent and easy to budget around.
