What happens if you miss a pay-later payment on a flight

If you miss a buy now, pay later (BNPL) payment on a flight, your trip itself is usually not affected: the lender paid the airline in full at checkout, so what you owe is a separate debt to the lender. What a missed payment costs depends on the provider. As of November 2026, Affirm, PayPal and Flex Pay (formerly Uplift) don't charge late fees, Klarna can charge up to $7 and Afterpay up to $8 per late installment, and a payment that stays unpaid long enough can end up on your credit report or with a collection agency.

The good news is that most missed payments can be fixed before they do lasting damage. Credit bureaus generally only see a late payment once it is 30 days past due, which gives you a window to catch up.

Missed-payment rules at a glance

Here is how five common providers compare on a missed payment, based on their own terms and help pages as of November 2026.

What happens to the flight itself?

When you pay for a flight with a BNPL loan, the lender pays the airline or travel site the full price at checkout, and you repay the lender over time. Your reservation is in place from day one, and the loan is a separate contract between you and the lender. Flex Pay's own FAQ puts it plainly: you can travel before you've finished paying.

That separation cuts both ways:

• A missed payment generally doesn't touch your reservation. The airline has already been paid. The lender's tools are late fees where its terms allow them, extra interest, account restrictions, credit reporting and, eventually, collections. If you bought a package through a travel seller, read that seller's terms as well.
• Cancelling the flight doesn't cancel the loan. If you cancel a non-refundable fare, airlines often give you a travel credit for a future trip instead of money back. That credit belongs to you, but the lender still hasn't been repaid, so your loan balance stays exactly where it was. Flex Pay's FAQ says that if you aren't eligible for a refund, you are still responsible for the outstanding balance.
• Refunds go to the lender, not to you. If the fare is refunded, the money goes back to the original form of payment, which is the loan. Flex Pay says it applies a merchant refund to your balance within 10 days of receiving it, that payments due in the meantime are still required, and that interest still accrues. A partial refund lowers your balance, but your monthly payment stays the same until the loan is paid off.
• Airline cancellations follow federal refund rules. Under the US Department of Transportation's automatic refund rule, in effect since October 28, 2024, if the airline cancels or significantly changes your flight and you turn down the alternative, the refund is due to your original payment method: within 7 business days for card purchases and 20 calendar days for other payment methods. With a BNPL purchase, that refund flows to the lender.

Provider by provider: what a missed payment costs

Affirm

Affirm doesn't charge late fees on any of its plans, and its site says you'll see any interest up front. Its monthly plans carry 0% to 36% APR depending on credit, and Pay in 4 is 0% APR.

No fee doesn't mean no consequences. Affirm began reporting all of its pay-over-time loans, including Pay in 4, to Experian for loans issued from April 1, 2025, and to TransUnion for loans issued from May 1, 2025. When it announced the change, Affirm said the new Pay in 4 data wouldn't be factored into traditional credit scores in the near term, but your payment history on those loans is now visible on your credit files. NerdWallet's review notes that Affirm takes outstanding payments into account when you apply for another Affirm loan, and that Affirm loans aren't charged off until they are 120 days past due. A seriously delinquent account can be sent to collections.

Klarna

Klarna's US Pay in 4 agreement (the version published June 3, 2026) spells out the process:

1. Retries. If a payment is rejected, Klarna may try it up to two more times. If you've set a backup payment method, it may try that too, with at least a day's notice.
2. Late fee. If a payment is still unpaid 10 days after its due date, Klarna can charge a late fee of up to $7, or less where the law requires.
3. Cap. Late fees on a single order never add up to more than 25% of the total purchase amount.
4. Default. If you default, Klarna may hand the debt to a collection agency, report the default to the credit bureaus and block you from using Klarna in the future.

Klarna's help center adds that a missed payment may be rolled into your next scheduled payment.

Klarna's monthly financing, which it calls Pay over time, is issued by WebBank and runs 3 to 24 months at 0% to 35.99% APR. Late fees and interest on those loans follow your credit agreement, the due date can't be extended, and Klarna reports repayment activity on them to the credit bureaus, including on-time, late and missed payments.

Afterpay

Afterpay's US installment agreement (last updated September 2026) sets these rules for Pay in 4:

• Late fee: if an installment is still unpaid 10 days after its due date, Afterpay can charge up to $8, and never more than your state's law allows.
• Cap: total late fees on an order can't exceed 25% of the order value at purchase.
• State exception: the agreement says no late fees apply to Rhode Island residents.
• Default: Afterpay can declare the loan in default and make all remaining payments due at once, limit or suspend your account, and use third-party collection agencies.

On credit reporting, NerdWallet's late-2025 review found that Afterpay doesn't report your payment history to the bureaus, so on-time payments won't build credit. The agreement still warns that negative information may be reported if you don't pay, so don't treat an Afterpay balance as invisible.

PayPal Pay in 4 and Pay Monthly

PayPal says neither of its pay-later products charges late fees. Pay in 4 splits a purchase into four interest-free payments every two weeks. Pay Monthly is a loan from WebBank with 3, 6, 12 or 24-month plans at a fixed 0% to 35.99% APR, for purchases from $49 to $10,000. As of November 2026, Pay in 4 isn't available to Missouri residents, and Pay Monthly isn't available in Alaska, Connecticut, Hawaii or Washington.

If you miss a repayment, the loan shows as past due and PayPal sends reminders. PayPal's help center says that once repayments begin you can't pause, suspend or skip them, though you can change the payment method used for future repayments. Missed repayments may hurt your eligibility for future pay-later offers, and PayPal says they may affect your credit score. NerdWallet's review reports that payments 120 days past due could be reported to the credit bureaus.

Uplift, now Flex Pay by Upgrade

Uplift, a pay-over-time lender that specializes in travel, was renamed Flex Pay on December 12, 2024, after Upgrade acquired it. Flex Pay's site lists airline partners including Southwest, United and Air Canada, and existing Uplift loans kept their dates, amounts and rates.

Flex Pay charges no late fees and no prepayment penalties. Its FAQ is clear about what happens instead:

• Interest keeps running. Every Flex Pay loan is a fixed-rate installment loan at 0% to 36% APR, and if you pay late you owe additional interest.
• Credit reporting. Flex Pay reports to Equifax, Experian and TransUnion, you can't opt out, and payments more than 30 days past due may be reported as late.
• No new loans. You can't get new Flex Pay financing until your payments are current.

A "no late fee" policy is not the same as "no cost": on an interest-bearing loan, paying late usually means paying more interest, with no separate fee to flag it.

Will a missed pay-later payment hurt your credit?

It can, but timing matters a great deal. According to Experian, creditors report late payments only once they are at least 30 days past their due date, and a payment brought current before then probably won't be reported. Once a 30-day late payment is reported, it stays on your credit report for seven years from the date you missed it.

BNPL reporting has expanded quickly, as the provider sections above show. In June 2025, FICO announced two new scores, FICO Score 10 BNPL and FICO Score 10 T BNPL, which lenders can use alongside the FICO versions they already rely on. Whether your BNPL history moves a particular score depends on which scoring model a lender uses, but a late payment or collection account on a monthly BNPL loan can weigh on your credit the way it would on any other loan.

Does buy now, pay later affect your credit score? goes deeper on soft checks, reporting and the new scores.

When does a missed payment go to collections?

There's no single timeline. According to NerdWallet, Affirm doesn't charge off a loan until it is 120 days past due, and PayPal payments that reach 120 days past due could be reported to the bureaus. Klarna may use a debt collection agency once you're in default under its agreement, and Afterpay can make your remaining payments due at once and appoint third-party collection agencies.

A collection account is one of the more damaging items on a credit report. Experian says that for a series of late payments, the late payments and any related collection accounts come off your report seven years after the first late payment in that series.

What to do before a payment fails: a checklist

Almost every option for getting more time works better, or only works, before the due date. If a payment is coming up and the money might not be there, go through this list.

1. Check the due date and funding source. Open the provider's app a few days before each payment. Confirm which card or bank account it will charge and that the money will be there that day.
2. Replace an expiring or replaced card. A card that expired, or was replaced after being reported lost, is one of the most common reasons an automatic payment fails. Update it in the provider's app before the due date.
3. Avoid bank fees on top of lender fees. If your BNPL payments come from a debit card or checking account, a failed payment can trigger a fee from your bank as well. Move money in ahead of time if you can.
4. Use the provider's own flexibility. Klarna lets you extend your next Pay in 4 payment date once per order, though not on its monthly financing. PayPal won't let you skip a repayment, but you can switch the payment method before it's charged.
5. Contact the lender before the due date. Klarna's app has a Financial support section for repayment options, and Upgrade asks Flex Pay customers who can't pay to call as soon as possible. Lenders generally have more options before a payment is late than after.
6. Don't borrow to repay. Taking a new BNPL loan, cash advance or payday loan to cover an existing payment usually adds cost and another due date to juggle.
7. Keep one list of every plan. If you have several plans running at once, a single calendar of every upcoming payment makes clashes visible before they happen.

What to do after a payment fails

If a payment has already been missed, work through these steps in order.

1. Pay the missed amount as soon as you can. If you can catch up within 30 days of the due date, the late payment is unlikely to reach your credit report. Paying part of it still lowers what's outstanding.
2. Fix whatever caused the failure. Update the card, move funds or switch the payment method so the next payment doesn't fail too.
3. Read the notice you received. It should say whether and when the lender will retry, and whether a late fee applies. With Klarna and Afterpay, the 10-day window before a late fee matters.
4. Ask about hardship options. If you can't catch up soon, tell the lender what's going on and when you expect to pay. Ask what will happen to your account and your credit if you agree to a plan.
5. Check your credit reports. Equifax, Experian and TransUnion let you check your reports free every week at AnnualCreditReport.com, according to the FTC. If a late payment is reported incorrectly, you can dispute it with the bureau.
6. If a collection agency calls, get it in writing. Ask for the amount, the original creditor and how the figure was calculated, and check it against your own records before you pay.
7. Keep records. Save confirmation numbers, emails and screenshots of every payment and every conversation.

How Defera handles a missed payment

Defera isn't a lender and doesn't run a credit check. It's a layaway-style payment plan: you pay for your trip before you fly, in automatic weekly or bi-weekly payments, with no interest. Your trip price is secured once your booking is approved and stays protected while you keep up with your plan. Because you pay before you travel, your airline confirmation number appears in Trips once the plan is paid in full, not at checkout. That's the main trade-off compared with a BNPL loan, along with the fact that every Defera trip departs at least 22 days after booking.

If a Defera payment doesn't go through, here's what the Help Center says happens:

• Your trip isn't cancelled on the spot. The payment shows as past due, your trip shows a past-due banner, and Defera may try your card again.
• There's no late fee. Nothing is charged for a missed payment on its own.
• You can catch up a little at a time. In Make a Payment, the Past due tab takes any amount from $5 toward your oldest missed payment. Once nothing is past due, your plan picks up its normal schedule. What happens if a payment doesn't go through walks through it.
• You can move the payment to payday. Missed a payment? Pick a day that works moves a missed payment to a later day you choose, within a set limit, for an Extension Fee that's spread across your remaining payments, so nothing is charged that day. The fee and the limits are in Moving a payment you can't make.
• You have options before a payment is due. Can't make your payment? does the same for an upcoming payment. On plans that show it, Skip Payment makes your next payment $0 for a fee charged that day, though it isn't available while something is past due; see Skipping a payment. If your trip shows Change Schedule, it switches you from bi-weekly to smaller weekly payments at no cost.

If a payment stays past due for a long time, the plan can pause, and your trip shows a Restart Plan option to get it going again. If payments fall far enough behind, a trip can default, which means its payment plan ends and automatic payments stop. There may still be a way forward on select bookings; What happens if my trip defaults? explains the options and how to ask.

On credit: Defera doesn't check your credit when you book, and doesn't report your plan or your on-time payments to the credit bureaus, so paying on time won't build credit either. What happens if a plan goes unpaid is set out in Defera's Terms of Service.
