UK airports prepare for busiest-ever summer – and these are the peak dates

As the great escape of summer 2025 begins, airports across the UK are predicted to handle more passengers than ever in July and August.

Exclusive research by The Independent reveals Fridays, Sundays and Mondays will be the most crowded days in the terminals.

The peak days for the great getaway for all the top UK hubs can be revealed using sources including the airports themselves and flight data supplied exclusively by aviation data analyst Cirium.

On Monday 1 September, the signal that the country is back to back to work is that London City’s busiest day is expected at the start of the ninth month. On that day 89 flights with 9,195 seats will depart from the Docklands airport.
