The terms list Visa, Mastercard and mada, bank transfers into Flyin's accounts, plus Flyin rewards or Qitaf points. The homepage promotes an instalment service that lets you book now and settle the bill later, and the payment page shows which options apply to your booking.
Selected hotels also offer “Book now, pay later”, which appears beside the online payment option. Be careful: if payment is not made by the stated deadline, the booking is cancelled automatically. When a booking paid with Qitaf points is cancelled, the provider's cancellation fees come out of the points, and what is left is credited to your wallet.
