Ryanair boss Michael O’Leary has advised cabin crew to watch their weight – in a bid to save on rising fuel costs.

The controversial airline chief has also reduced the size of his in-flight magazine, cut the amount of ice served with drinks, and considered removing armrests.

The budget airline is also in favour of a fat-tax on heavier passengers who would be asked to pay more for their seats.

As fuel prices rise dramatically, the airline has admitted it is taking extraordinary measures to save costs.

“We cut costs wherever possible, and the changes will represent a significant reduction in weight,” said Ryanair spokesman Stephen McNamara in an interview with the Irish Independent

“We also considered removing armrests, but decided against it. We even encourage staff to watch their weight - with the motivation of appearing in the annual Ryanair calendar.”

New measures include cutting the size of the in-flight magazine which will also save on its printing bill.

Cabin crew are to serve less ice with drinks while trolleys and seats are to be reduced in weight.

McNamara did confirm that Ryanair is committed to its promise not to introduce fuel surcharges unlike other airlines.

“Fuel is an integral part of the fare - you can’t fly passengers anywhere without it,” added McNamara.

“We would rather make cost reductions and charge passengers for other services.”
