Ryanair customers have been told they need to pay more for flights they have already booked and paid for. Those who booked to fly from Friday, April 1, will be affected.
Liverpool Echo reports customers were emailed by the airline in which they were told how much extra they would need to pay.
The email says that in March Belgium introduced a new flight tax departing the country from April 1. "This means that even if a passenger booked a flight before 25 March, which is due to depart Belgium on or after 1 April, we must pay this new tax to the Belgian government.
