Airline is yet to produce a timetable for the route for 2025
easyJet is not currently offering flights between the Isle of Man and Belfast after the end of next month.
Passengers can’t book travel past 25 October.
The Bristol route has also been suspended between 30 September and 31 March.
The airline's services to other routes from Ronaldsway – including Manchester, London and Liverpool – can be booked up to September 2025.
easyJet has told Manx Radio: “For the moment the dates are not confirmed yet,” adding it releases flights on a regular basis so passengers should refer to the airline’s website.
