Booking plane tickets can be stressful enough without staring at the total and wondering if you can swing it. That’s where “fly now, pay later” options step in. Instead of paying the entire upfront cost of your flight tickets, you can spread it out through an installment-based payment plan. It sounds simple, but there’s a lot happening behind the scenes. However, with top airlines like Allegiant, Delta, Southwest, and United all offering FNPL options, it’s worth investigating.
In this guide, I’ll walk you through the exact process, from decision-making to post-checkout, so you know exactly what to expect—and whether fly now, pay later is right for your next trip.
Key Takeaways
- Step-by-Step Process: Fly now, pay later starts at checkout, where you select a BNPL payment method instead of paying upfront.
- Quick Approvals: Providers usually require only basic info and run a soft credit check, so applying won’t hurt your score.
- Immediate Ticketing: Airlines issue your flight tickets once a down payment is made, covering your travel expenses immediately.
- Potential Risks: Missed payments can lead to late fees, suspended accounts, or loss of access to the buy now, pay later service.
- Know the Details: Flexible payment options help spread costs, but hidden fees or restrictions (like on multi-city flights) may apply.
Step 1: Choosing a Payment Method
When you’re booking flights online, you’ll see different checkout options. Alongside credit cards and debit cards, you may see BNPL choices like Sezzle, Affirm, Klarna, or PayPal Pay Later payment plans. Selecting one tells the payment provider you’d like to divide the cost instead of paying all at once.
Depending on the company, you’ll get choices like:
- Four interest-free installments over six weeks.
- A longer monthly plan with 3, 6, or 12 monthly installments.
- Custom terms with flexible payment plans, sometimes tied to your trip length or total.
Step 2: Quick Approval
Once you choose your payment option, the provider asks for a few basics: your name, email, and sometimes a mobile phone number. They may also request a few details, like your date of birth or address, to verify your identity.
Instead of a full credit pull, most services run only a soft credit check, which won’t impact your score. If approved, you’ll see the total divided into smaller chunks, along with a clear payment schedule.
Step 3: Down Payment and Ticket Release
Before your ticket is confirmed, you’ll usually need a down payment. Think of it as a deposit—it locks in your fare while signaling to the provider that you’re serious. The airline then issues your ticket, and your travel expenses immediately hit the BNPL account. From there, your upcoming payments roll out on the agreed schedule.
Step 4: Handling the Payments
Your flights are covered right away, but you’re now committed to those installment payments. Providers usually give you the option of linking a debit card, credit card, or bank account for auto-pay. If you stick to the plan, it’s smooth sailing.
Miss a date, though, and you could face late fees. Repeated missed payments may even suspend your account with that provider, keeping you from using their service in the future.
Step 5: Extra Details to Watch For
Like any financial product, there are pros and cons:
- Flexible Payment Options: You can choose between short-term or long-term splits, depending on your budget.
- Hidden Fees: Some BNPL programs advertise low cost but may include service charges if you extend your plan.
- Save Money Strategies: Sometimes, paying off your plan early avoids interest altogether.
- Multi-City Flights: Not all providers allow you to book multi-city flights on BNPL, so check before planning complex routes.
Final Thoughts

Fly now, pay later can take the sting out of rising flight prices, but it’s not free money. You’re still on the hook for those monthly payments, and skipping them can mean fees or blocked accounts. Used wisely, though, BNPL makes it easier to spread out flight purchases and travel when you need to, instead of waiting until you’ve saved up.
If you budget carefully and understand the terms, these programs can be a handy way to see more of the world—without emptying your bank account before you even board the plane.
