Travel is not exactly cheap in 2023, but our recent partnership makes it easier to finance over time. With KAYAK and Affirm, travelers can find the travel options that fit their needs and choose from payment options that work for their budget. Had your eye on a set of flights? Choose the “Instant book” option and select “Affirm” as your payment to explore your pay-over-time options. Head to the official KAYAK and Affirm page for more details on how to use this new feature.
