The airline said the planned outage will run from 11 p.m. on Feb. 25 until 8 a.m. on Feb. 26, Hungarian time.

During that period, several services will be unavailable, including the purchase of new tickets, management of existing bookings, online check-in, booking functions within the Wizz Air mobile app, voucher redemption and services linked to customer profiles.

The carrier emphasized that flights will operate according to schedule and that passengers who complete online check-in before the outage will not be affected.

Wizz Air advised travelers who have not yet checked in for their flights to do so before the maintenance window begins. If necessary, airport check-in will be available free of charge during the system update period.
