Monarch scheduled flights will be unavailable on Worldspan and Sabre from June 1 when the carrier withdraws from the UK Billing and Settlement Plan (BSP).
However, the airline will remain bookable via Amadeus and Galileo using an alternative Instant Pay system.
Agents will be required to enter the details of their own or their customer’s credit card on the booking. Monarch said bookings would not be confirmed without this.
The system will be in operation for sales via Amadeus and Galileo from Monday. [May 19]
An airline spokeswoman said: “We decided to withdraw flights from Worldspan and Sabre as we have noticed a significant fall in business and Amadeus and Galileo are strongest in our core market.”
Monarch will emulate EasyJet by signing non-GDS suppliers to its Application Programming Interface (API), which aims to stop search engines screen-scraping online fares.
“We are looking to work with partners with whom we can connect on an API basis,” said the airline. “Galileo and Amadeus have this functionality.”
An ABTA spokeswoman suggested many agents already book Monarch flights on the carrier’s website.
