The operator is continuing to direct more agent queries away from its call centre and towards its self-serve tools instead.
Back in April, Jet2 said agents would in future be required to use its Manage My Booking platform for most post-booking changes.
It has now extended the platform's scope to allow agents to amend bookings, hotel reservations, ancillaries and documents themselves, as well as manage assisted travel and promo codes, and advise on terms and conditions.
