Latest aviation trends data shows UK aviation had the highest ever passenger numbers in the first quarter of 2026.

This growth was largely driven by short-haul European flights, with over one million additional passengers travelling to Western Europe.

Is your luggage lost, delayed or damaged? This is the responsibility of the airline. The amount you are entitled to will depend on the value of the lost goods. Most airlines will also reimburse you for the bare essentials you may need to buy as a result of delayed luggage. For more information, visit our website. Sometimes when you get to your destination airport, your baggage does not appear on the carousel.

Flight delayed? Here's what you need to know. If your flying from a UK airport or if you're coming back on a UK or EU airline and are significantly delayed, your airline must look after you with food, drink, a way to communicate, such as access to a phone or email, and if delayed overnight, a hotel and transport. This applies after two hours for short flights, three hours for medium distances, and four hours for long-haul. Can't get help?

The UK Civil Aviation Authority (CAA) has today launched a consultation on a shortlist of regulatory models that could apply to capacity expansion at Heathrow Airport.

Flight cancelled? We know it's stressful — here's what you need to know to make sure you're looked after. If your flight departs from the UK, or arrives here on a UK or EU airline, you have rights. Your airline must provide you with care and assistance while you wait. That means food and drink vouchers, help with communication costs and, if needed, accommodation and transport.
