Irish carrier Aer Arann has announced it will introduce a fee for hold baggage on all bookings from tomorrow (April 27).
Aer Arann said it was responding to "customer feedback and passenger trends".
Aer Arann is also increasing its fees on amendments to bookings, such as route, time or date changes from £20 to £35, or £50 if made at the airport. The fee for changing the name on a ticket is increasing from £32 to £100.
The Dublin-based regional airline's current baggage allowance is currently 15kg per passenger on all flights.
Travellers on domestic flights (within Ireland) will still be entitled to 15kg free. But passengers on flights to the UK and France will be forced to pay £8 per bag, with a higher weight limit of 20kg, if booked online.
Passengers arriving at the airport without pre-booking will pay £12 for each bag they want to check in.
Aer Arann said it believes its international passengers would "prefer" a 20Kg allowance with one bag fee, but that "domestic passengers are happy with a lower free allowance as trips away tend to be shorter".
Andrew Kelly, Aer Arann's Director of Corporate Affairs, "We found that while passengers appreciated the free baggage allowance they wanted a larger 20kgs allowance on international flights.
"Prior to this change in policy a passenger with a 20Kg bag would have been liable for excess baggage charges of €40."
Flights between the Isle of Man and London City will remain an exception - passengers on this route will get 20kg of checked baggage allowance for free.
For domestic passengers connecting to or from international carriers, Aer Arann has said it will "continue to honour" the free baggage allowance of their connecting airline, provided they present their onward itinerary at check-in.
Excess baggage will be charged, per kg, at £7 - up from £6.50.
The policy for hand baggage remains unchanged: One piece of cabin baggage per passenger, which must not weigh more than 7 Kg and comply with size restrictions.
