Pay Monthly for Flights in 2026
Pay monthly for flights using buy now pay later providers that split airfare into installments. Five providers support flight payments in 2026: Sezzle Pay in 4 (zero interest, 4 payments over 6 weeks on 750+ airlines via Travorio), PayPal Pay in 4 ($30-$1,500 US only), Affirm (monthly plans at 10-36% APR via Priceline), Southwest FlexPay (Southwest flights only), and United FlexPay (United flights only).
Most travelers searching for monthly flight payments want to avoid paying $500-$1,500 upfront for airfare. The options vary significantly in cost. Sezzle and PayPal charge zero interest on their 4-payment plans. Affirm charges interest on plans longer than 4 payments, adding $18-$210 to a $300-$1,500 flight depending on term length and APR. Airline-specific plans (Southwest, United) have no interest but limited airline coverage.
This guide compares all 5 options with pricing examples, credit check requirements, and step-by-step booking instructions.
Option 1: Sezzle Pay in 4 on Travorio (Recommended)
Sezzle splits any flight into 4 equal payments over 6 weeks. Zero interest when paid on time. Soft credit check only. Works with all 750+ airlines on Travorio including Delta, United, American Airlines, Southwest, JetBlue, Spirit, Frontier, and international carriers.
Payment example: A $600 New York to London flight costs $150 per payment. First payment due at booking, then $150 every 2 weeks for 6 weeks. Total cost: $600. No interest added.
Sezzle is available to US and Canada residents. Approval is based on Sezzle account history and a soft check that does not affect your credit score. First-time users typically get $500-$1,000 spending limits.
Option 2: PayPal Pay in 4
PayPal Pay in 4 splits flights into 4 payments over 6 weeks. Available on Travorio for bookings between $30 and $1,500. US customers only. Zero interest when paid on time.
PayPal Pay in 4 uses your existing PayPal account. Approval is per-transaction at checkout. If your flight exceeds $1,500, PayPal Pay in 4 is not available and you should use Sezzle instead.
Option 3: Affirm (Monthly Plans with Interest)
Affirm offers longer monthly payment plans (3-36 months) for flights on Priceline and CheapOair. Interest rates range from 10-36% APR depending on your credit profile and plan length.
Payment example: A $600 flight on a 12-month Affirm plan at 25% APR costs $57/month for 12 months, totaling $684. You pay $84 in interest. Affirm performs a hard credit inquiry for larger purchases.
Affirm is the only option for true monthly payments over 6+ months. The tradeoff is interest charges and a credit score impact from the hard inquiry.
Option 4: Southwest FlexPay
Southwest FlexPay splits Southwest-only flights into 3 payments. First payment at booking, second 30 days later, third 30 days after that. No interest. No credit check.
The limitation is airline coverage: FlexPay only works on southwest.com for Southwest Airlines flights. You cannot use it for any other carrier. Available for US domestic routes only.
Option 5: United FlexPay
United FlexPay splits United Airlines flights into monthly payments via Uplift. Interest rates vary (7-36% APR). A credit check is required.
United FlexPay offers longer terms (up to 12 months) but charges interest on every plan. It only works for United Airlines flights booked on united.com.
Which Option Is Best for You?
For most travelers, Sezzle Pay in 4 on Travorio is the best choice: zero interest, 750+ airlines, soft credit check. If your flight is under $1,500 and you have a PayPal account, PayPal Pay in 4 is equally good.
Choose Affirm only if you need longer payment terms (6-36 months) and are willing to pay interest. Choose Southwest or United FlexPay only if you exclusively fly that airline.
