Does buy now, pay later for flights affect your credit score?

It can, though usually not when you apply. Affirm, Klarna, Flex Pay (formerly Uplift) and PayPal Pay in 4 all say that checking your eligibility uses a soft check or doesn't affect your score, and Afterpay runs a soft check when you sign up. What happens afterward varies: as of November 2026, Affirm reports all of its loans to Experian and TransUnion, Flex Pay reports to all three major bureaus, Klarna shares its term loans with TransUnion, PayPal may report Pay Monthly loans, and Afterpay says it doesn't report to US credit bureaus at all. On-time pay-later payments mostly aren't counted in the credit scores lenders use yet, but late payments can be reported, and a debt sent to collections can do lasting damage.

Below, we go provider by provider, explain what's reported and what's actually scored, cover what changed in 2025 with FICO and the Consumer Financial Protection Bureau (CFPB), and finish with practical steps for using pay-later on a flight without hurting your credit. Provider details come from each company's own site, as of November 2026.

Does buy now, pay later affect your credit? The answer by provider

This is what the five providers you're most likely to see when booking a flight say about credit checks and credit reporting.

Two things the table can't show. First, reported isn't the same as scored: some of this data sits in your credit file without counting toward the scores lenders use, as we explain below. Second, policies change, and your own loan agreement is the final word on what's reported for your plan.

Soft vs hard credit checks: what pay-later lenders run

There are two kinds of credit check, and they affect your score differently:

• A hard inquiry happens when a lender reviews a credit application. The CFPB says hard inquiries will affect your credit score, because scoring models look at how recently and how often you apply for credit.
• A soft inquiry happens with things like prescreened offers, account reviews and checking your own report. The CFPB says soft inquiries won't affect your credit scores.

For the eligibility step, the big pay-later providers say they use soft checks or no score impact. Flex Pay goes further and says it doesn't perform hard credit inquiries at all. Klarna says its soft checks don't affect your score and aren't visible to other lenders, and that TransUnion performs them. Afterpay says it may run a soft check when new customers sign up, and that it also does a credit check if you choose its Pay Monthly option, without saying in that article which kind.

That's a real difference from applying for a credit card or a personal loan, which usually means a hard inquiry. But the check is only the first step. For your credit, what matters more is what's reported after you take the plan, and whether you pay on time.

What gets reported: on-time payments, late payments and new accounts

Here's what each provider says it reports, in more detail.

Affirm. Affirm's help center says that since April 1, 2025, all payment activity, including on-time, late and missed payments, is reported to Experian, and that plans started on or after May 1, 2025 are also reported to TransUnion. That includes Pay in 4. Plans that started before April 1, 2025 may or may not have been reported, depending on the type of plan, and Affirm says a reported plan's payments can take 30 to 60 days to appear on your credit report.

Flex Pay (formerly Uplift). Flex Pay's FAQ says it currently reports to Equifax, Experian and TransUnion. For US residents, a payment more than 30 days past due is reported to the credit bureaus as late.

Klarna. Klarna began sharing data on its Term Loan financing with TransUnion from November 1, 2024. At the time, it said the data would be visible to you but would not affect your credit score, and that Pay in 4 payments were not part of what it shares. Klarna also says late or missed payments could hurt your creditworthiness and can stop you using its payment options.

PayPal. PayPal says it may report Pay Monthly loans to the credit reporting agencies, where they can appear under its lending partner's name, WebBank. Its Pay in 4 pages describe a soft check that doesn't affect your score.

Afterpay. Afterpay's US help center says it doesn't currently report to credit bureaus in the United States.

Each pay-later plan can also show up as its own account. FICO's research found that people often open several BNPL loans in a short time, which is one reason its new BNPL scores, covered below, combine them in some calculations rather than treating each one as a separate new debt.

Do BNPL payments count toward your credit score yet?

For the most part, not yet, at least in the scores most lenders use. When Affirm expanded its reporting with Experian in March 2025, the companies said the newly reported loans would not be factored into traditional credit scores in the near term, though they may be in the future as new scoring models are developed. Klarna said the same about its Term Loan data in 2024.

In practice, that means:

• On-time payments may not help yet. Paying an Affirm plan on time builds a record in your Experian and TransUnion files, but it may not raise the score a lender pulls today.
• Your report and your score are different things. Your credit report is the record. Your score is a calculation a lender runs on that record, using a scoring model the lender chooses.
• Late payments can still matter. A provider like Flex Pay reports loans to all three bureaus and reports payments that are more than 30 days late, and an account that ends up with a collection agency is serious under any model.

If your goal is to build credit, a pay-later plan for a flight is an uncertain way to do it as of November 2026. Whether a given plan helps depends on the provider, the bureau and the score your future lender uses.

FICO’s BNPL credit scores: what changed in 2025

In June 2025, FICO announced two new scores that include buy now, pay later data: FICO Score 10 BNPL and FICO Score 10 T BNPL. They're new versions of the score, built to take BNPL loans into account, rather than changes to the scores lenders already use.

The main design choice is how they handle lots of small loans. Because people often open several BNPL loans at once, the models combine concurrent BNPL loans in certain calculations, so a string of small plans doesn't automatically look riskier than one larger debt. In FICO's analysis, which included Affirm data on more than 500,000 consumers, 85% of BNPL users saw score changes of fewer than 10 points, and 97% of highly active users (five or more BNPL accounts) saw changes of fewer than 20 points.

Adoption is the open question. As of FICO's March 2026 update, the models were to be made available at the credit bureaus at the same time the bureaus make BNPL data widely available in credit reports, and lenders choose when to switch on the BNPL component. Lenders also tend to stick with older score versions, because switching is costly. In September 2025, an analyst at LexisNexis Risk Solutions told Digital Transactions it could be years, if ever, before BNPL activity is fully and consistently reflected in the scores that decide credit, partly because reporting by BNPL lenders is voluntary and several have said they don't plan to report Pay in 4 loans.

What happened to the CFPB’s buy now, pay later rule?

On May 22, 2024, the CFPB issued an interpretive rule saying that buy now, pay later lenders are credit card providers under the Truth in Lending Act. That meant giving BNPL borrowers some of the same protections as credit card holders:

• investigating disputes you raise, and pausing payments while they investigate;
• crediting refunds to your account when you return something or a service is cancelled;
• sending periodic billing statements.

The rule didn't last. On May 12, 2025, the CFPB withdrew a set of guidance documents, including the 2024 BNPL interpretive rule.

Two practical points follow. First, the rule was about disputes, refunds and statements, not credit reporting, so its withdrawal doesn't change what providers report; reporting by BNPL lenders was voluntary before and remains so. Second, for flights it matters most when something goes wrong: if your flight is cancelled and refunded, how quickly the refund reaches your loan, and whether you can pause payments while you dispute, depends on your lender's own terms. Flex Pay, for example, says it applies a travel refund to your balance within 10 days.

How late payments and collections affect your credit score

Payment history is the single biggest part of a FICO Score, at 35%. Here's how a missed pay-later payment can turn into a credit problem:

1. The payment is missed. At first this is between you and the lender. Some providers retry the payment or charge a late fee, and some stop you from making new purchases until you catch up.
2. It becomes reportable. myFICO says creditors typically report late payments in steps: 30, 60, 90, 120 or 150 days late, or as a charge-off. Flex Pay, for example, reports a payment as late once it's more than 30 days past due. Affirm reports missed payments to Experian along with on-time ones.
3. It goes to collections. If the debt is charged off or sent to a collection agency, myFICO calls it a significant event that's likely to have a severe negative effect on your score. Before that point, you can recover by getting current. After it, the account can never be brought current again.
4. It stays on your report. The CFPB says credit reporting companies can generally report negative payment history for up to seven years.

How much any one late payment moves your score depends on how recent, how severe and how frequent your late payments are, and on which scoring model a lender uses. A single payment that's caught up within days usually never reaches a credit report at a provider like Flex Pay. One that runs 60 or 90 days late, or ends up in collections, is a different matter. What happens if you miss a pay-later payment on a flight goes through each provider's late fees and timelines.

How to use pay-later for a flight without hurting your credit

If you do use buy now, pay later for a flight, these steps keep it from becoming a credit problem:

1. Check eligibility before you commit. It's a soft check at the major providers. Then read the plan terms to see whether the loan will be reported.
2. Count every plan you already have. Add up all your pay-later due dates across apps before you add a flight. Several small plans due in the same week make it easy to miss one.
3. Use autopay from an account with room. Set a reminder a few days before each due date, especially if your income is irregular.
4. Contact the lender before a due date, not after. Your options are better while you're still current.
5. Keep paying until a refund posts. If your flight is cancelled and refunded, the money goes to the lender. Keep making payments until the lender confirms it has reduced your balance.
6. Check your credit reports. You can get your reports for free at AnnualCreditReport.com. Affirm says reported plans can take 30 to 60 days to appear, and points borrowers to the credit bureau disputes section of their loan agreement if something is wrong.

Where Defera fits

Defera isn't a lender, and it doesn't check your credit to let you book: there's no credit score involved and no hard or soft credit pull. Defera also doesn't report your payment plan or your on-time payments to the credit bureaus, so paying on time with Defera won't help build your credit. If a plan goes unpaid, what happens is set out in Defera's Terms of Service.

Defera's plans are layaway-style: you pay a deposit when you book (or nothing with Defera Zero, on refundable fares on select airlines), then automatic weekly or bi-weekly payments, with no interest. Once your booking is approved, the agreed-upon trip price is secured while you stay in good standing, and your airline confirmation number appears in Trips once the plan is paid in full. Every Defera trip departs at least 22 days after booking. Is there a credit check? has the details.
