The reassurance follows an announcement of new European rules on baggage transparency, set by the European Commission and due to take effect in 2027.
These rules aim to improve clarity around luggage policies, helping passengers understand what is included in their fare.
Jet2 customers already receive a free 10kg hand luggage allowance as standard, alongside a personal item.
Steve Heapy, chief executive of Jet2, said: “For Jet2 customers, these new rules change nothing because we have always believed in doing the right thing by customers when it comes to hand luggage.
“Holidaymakers should not have to pay extra or figure out complicated rules just to bring their essentials on board.
“We have always believed in making things simple, transparent and fair, so customers know exactly what they’re getting when they book.”
Mr Heapy welcomed the European Commission’s efforts to improve transparency across the airline industry.
He said: “We welcome any move that helps customers better understand what is included in the price of their flight and make informed decisions when comparing airlines.
“It is another example of why customers continue to choose Jet2 in record numbers – because they know exactly what they’re getting when they book.”
According to Jet2, 80% of customers say the inclusion of 10kg of free hand luggage is a key reason they choose to fly with Jet2.
The company was recently named the highest-rated airline and tour operator in the UK Customer Satisfaction Index (UKCSI) for July 2026.
