in3 TUI payment example
Peter is booking return flights from Amsterdam to Curaçao. He searches through Alternative Airlines and finds TUI fly Netherlands tickets available for €996.
Rather than paying the full amount up front, he looks at the buy now, pay later options at checkout. Then selects in3.
Now the cost of his TUI flights looks like this:
- At checkout: €332
- 30 days later: €332
- 60 days later: €332
Because Peter chose in3, which is interest-free, and paid back on time, the total he pays won't exceed €996.
