As a general rule, passengers travelling from Heathrow Airport should arrive at least 2 hours before a short-haul flight and 3 hours before a long-haul flight. This provides enough time for check-in, baggage drop, security screening, and reaching your departure gate comfortably.
The recommended arrival time may vary depending on your airline, destination, terminal, and travel season. During busy periods, such as school holidays, bank holidays, and peak summer travel, Heathrow Airport can experience higher passenger volumes, making it sensible to allow additional time.
If you're travelling with checked luggage, young children, mobility assistance requirements, or oversized baggage, arriving earlier can help make your airport experience more relaxed and convenient.
When planning your journey to Heathrow Airport, it's important to consider potential traffic delays, roadworks, and peak-hour congestion. Booking your airport transfer in advance can help ensure you arrive at the terminal with plenty of time before departure.
