Ryanair is raising checked-in baggage fees for July and August to €20 per bag, for all bookings made after midnight tomorrow.
In a statement the airline said it was doing this to encourage passengers to travel light during the peak summer months.
Checked-in bag fees remain at €15 for passengers not travelling in July and August.
Ryanair urged all of its passengers to avoid checked-in baggage fees by travelling with carry-on bags only using its free 10 kilogrammes carry-on baggage allowance.
