Millions of British holidaymakers could benefit from a series of airline rule changes expected to be introduced during 2027 as part of proposed UK aviation reforms and wider EU passenger-rights updates. The measures, designed to give travellers greater protection and consistency when flying, cover everything from airline baggage allowances to compensation claims and booking mistakes. Collectively, the changes could save a family of four just under £700 in additional airline charges, including seat selection fees, booking amendment costs and cabin baggage charges.
While some changes still require final approval and implementation dates vary, travellers are expected to see a number of them rolled out during 2027. However, those heading abroad this winter should still be aware of existing travel requirements, including passport validity rules, the Entry/Exit System (EES) and the upcoming ETIAS travel authorisation scheme, which currently does not have a confirmed start date after previous projections for late 2026 once again slipped.
Children seated with parents at no extra cost
Jane Bolton, travel expert at Erna Low, has explained the biggest travel updates holidaymakers should have on their radar for 2027. One confirmed UK rule change would entitle children under 14 to sit next to an accompanying adult without paying additional seating fees. Ms Bolton noted that families have long faced the frustration of being charged extra to sit together, with some departures experiencing delays due to last-minute seating swaps. In some cases, a family of four could pay as much as £250 to secure seats together on return flights.
While there is currently no law requiring children to be seated next to an accompanying adult, Civil Aviation Authority (CAA) guidelines state there should be no more than one row between a child and parent to prevent evacuation delays. Ms Bolton warned that the change is not yet in force, and until an implementation date is confirmed, families should continue to check the individual airline's seating policy before booking. For families travelling during school holidays or busy periods, this should remove one of the most common extra charges encountered when booking flights.
Free corrections for simple name mistakes
Another confirmed UK rule change would allow passengers to correct minor booking mistakes without facing penalties. According to Ms Bolton, small errors, such as simple name mistakes when booking, can add up to £40 to the cost of a flight due to airline administration fees, on top of already expensive costs for flights, transfers and hotels. She said the proposed reforms would help travellers avoid unnecessary costs for genuine errors.
However, this should not be confused with transferring a ticket to an entirely different passenger, which may still be subject to separate airline rules and charges. Ms Bolton advised that it is still worth checking booking details carefully, but passengers should have more protection when genuine errors occur.
Cabin baggage included in standard ticket price
One of the most significant incoming changes from the EU, expected in October 2027, is the move towards more standardised hand luggage allowance. Under the proposed reforms, passengers would be entitled to one small personal item that fits under the seat and one cabin bag weighing up to 7kg as part of the standard ticket price, helping to make baggage allowances and flight pricing more transparent. Ms Bolton explained that some airlines currently charge just under £50 each way to add a cabin bag, which can add significantly to flight costs, especially for families.
The new allowances would make comparing flight prices much easier and reduce the risk of hidden fees increasing the total holiday cost.
Missing an outbound flight won't cancel your return journey
Another EU rule expected in 2027 would prevent airlines from automatically cancelling a passenger's return flight if the outbound leg was unused. Ms Bolton said many travellers are unaware that missing an outbound flight could sometimes put the remainder of their travel plans at risk under some airline terms. The proposed reforms would provide holidaymakers with much greater flexibility for when travel plans don't go according to plan, particularly if they've experienced disruptions or delays.
However, with no confirmed implementation date, she urged travellers to still contact their airline immediately if they are unable to take an outbound flight, warning that passengers should not assume their return booking will remain valid under today's rules.
