As Heathrow Airport continues to adapt to the evolving landscape of air travel, significant changes have recently emerged that impact both passengers and airlines. Just before the rollout of new security measures, Heathrow announced that passengers flying from the airport can now carry up to two litres of liquid in their hand luggage, a change facilitated by the introduction of next-generation CT scanners.
On October 1, 2023, Heathrow Airport became the largest airport in the world to fully implement these advanced CT scanners, which allow for a more efficient security process. Passengers travelling through all terminals no longer need to remove liquids or electronics from their hand luggage, or juggle plastic bags at security. This innovation has been met with enthusiasm, as one passenger noted, “Makes things so much easier. You can just leave everything in your bag – even your laptop.” However, some caution that this convenience is contingent upon other airports adopting similar measures, as one traveler remarked, “This only works if every airport does it. It’s fine going out, but if your return airport still has the old rules, you’ll end up throwing things away.”
In a contrasting development, April 18, 2026, marks the suspension of Saudia’s route from London Heathrow to Dammam. This decision follows a challenging period for the airline, which had relaunched its flights on this route in November 2025 after a hiatus since 2010. Despite the initial optimism, Saudia’s Dammam-London Heathrow route struggled to gain traction, with an average load factor of only 49.5% in November and December 2025. Industry analysts suggest that the airline was likely operating at a loss on this route, prompting the suspension.
Additionally, Heathrow Airport reported that passengers paid a staggering £751 million for parking in 2025, highlighting the airport’s significant revenue from this service. The cost for long stay parking at Heathrow is £46.80 for two to 24 hours, although the first 30 minutes of long stay parking is offered for free, providing some relief for those picking up or dropping off travelers.
These developments at Heathrow Airport underscore the ongoing changes in the aviation sector, particularly in response to passenger needs and operational efficiencies. The introduction of new liquid regulations aims to enhance the travel experience, while Saudia’s route suspension reflects the challenges airlines face in maintaining profitable operations amidst fluctuating demand.
As Heathrow continues to innovate and adapt, the implications of these changes are significant for travelers and airlines alike, shaping the future of air travel from one of the world’s busiest airports.
