Heathrow urges passengers to declare medical conditions before flying

Passengers flying from Heathrow this summer have been told to check their travel insurance covers any existing medical conditions. The airport issued the warning after officials said uninsured travellers could face bills of more than £25,000 for emergency treatment abroad.

Heathrow’s official X account posted a message on 12 June 2025 advising passengers to declare conditions to their insurer. The post said: "Check you've declared any existing medical conditions with your insurer, to ensure you don't invalidate your insurance, leading to a big medical bill."
