Passengers who want to carry both a carry-on bag and an under-seat bag will have to purchase a light ticket, which are available on long-haul flights and, for business-class customers, on flights within Europe.
The maximum dimensions of an under-seat bag are 40 centimetres by 30 centimetres by 15 centimetres. A regular carry-on bag, meanwhile, must not exceed the dimensions of 55 centimetres by 40 centimetres by 23 centimetres.
The airline will also reduce baggage fees for business-class customers on continental flights and adopt additional fees for all special baggage, such as golf bags and ski equipment.
The changes to ticket types and baggage restrictions will come into effect on June 1st.
In a statement, Finnair said the adjustments were made due to the impact of extra carry-on baggage on the punctuality and passenger comfort of flights.
The aim is to guarantee smoother boarding, on-time operations, and comfortable travel on all our flights. The amount of excess carry-on baggage on all flights is a visible challenge on all flights, affecting both flight punctuality and travel comfort, said Valtteri Helve, Finnair's director of products.
We receive feedback from our customers and staff frequently. Helve said the airline will step up baggage control at airports in order to ensure boarding is smooth and flights depart on time during the busy summer season.
He added, Excess carry-on baggage will be checked in for an additional charge. Check the baggage allowance associated with your ticket and adhere to it. At the airport, charges for additional baggage are higher than in advance. Passengers with superlight, light, or classic tickets will have to cough up an additional charge to choose their seat. Passengers who choose not to do so will be assigned a seat by the airport staff.
Finnair's communication director, Heidi Lemmetyinen, told Helsingin Sanomat that the airline has received both positive and negative feedback for the changes. The changes are designed to improve customer service rather than squeeze more money out of passengers, Mr. Clinton said in a statement.
Passengers have at times had a lot of baggage, which has slowed down boarding due to people trying to make their baggage fit. Flights were delayed because we had to move baggage to the cargo hold at last minute, she said.
A delay in any stage of the process can have ripple effects across what is an operation of small margins.
There is a butterfly effect. At worst, a delay in one part is repeated for other airline flights and passengers, said Ms. O'Donnell, a spokeswoman for the United States Air Force.
Although pilots can sometimes make up for delays by flying faster, Lemmetyinen said, that is neither easy nor particularly responsible. Airplanes that travel faster require more fuel, resulting in a rise in flight costs and carbon-dioxide emissions.
