UK aviation surges past pre-pandemic levels as airports post record passenger numbers
The UK’s aviation sector is on course for its busiest year ever, with passenger traffic soaring to unprecedented levels and operational performance showing marked improvement. According to the Civil Aviation Authority (CAA), 141 million passengers travelled through UK airports in the first half of 2025—81 million of those between April and June alone, the highest quarterly figure on record.
This surge signals a full recovery from the pandemic-era slump, with demand now exceeding 2019 levels across many routes. Short-haul destinations such as Dublin, Amsterdam, Palma de Mallorca and Alicante have played a key role in driving growth, while punctuality has improved significantly. The CAA reports that 75% of flights are currently departing on time, up eight percentage points from 2024, with April peaking at 82%.
Selina Chada, group director for consumers and markets at the CAA, described the figures as “a great achievement,” attributing the rebound to strong consumer demand and industry-wide efforts to enhance reliability. “Reliable, on-time flights remain a priority, and it’s encouraging that delays are falling year-on-year,” she added.
Heathrow leads Europe in punctuality
London Heathrow remains the UK’s busiest airport, handling nearly 40 million passengers in the first half of the year. It has also emerged as Europe’s most punctual major hub, outperforming rivals in Amsterdam, Paris and Frankfurt. The figures bolster Heathrow’s case for expanding capacity, with renewed calls for a third runway to maintain competitiveness.
Tim Alderslade, chief executive of Airlines UK, said the data underscores aviation’s role as a “growth engine for the UK,” supporting regional economies and delivering improved service standards.
Regional airports and cargo show resilience
Northern airports have also posted strong gains. Liverpool, Manchester, Newcastle and Leeds Bradford collectively welcomed 750,000 more passengers than in the same period last year. Karen Dee, chief executive of AirportsUK, noted that “air travel sits at the heart of the economy,” connecting people and businesses while facilitating global trade.
British Airways reported a 48% rise in operating profits to £84 million for the first half of 2025, despite a £40 million setback caused by a temporary closure at Heathrow in May.
Cargo volumes have also rebounded, with a 6% year-on-year increase and nearly 700,000 tonnes shipped in Q2. Routes to Mumbai and Delhi saw the strongest growth, with volumes up 61% and 41% respectively. Dubai, New York, Doha and Leipzig remain key freight destinations.
Investor confidence returns to UK airports
The sector’s robust performance is restoring investor confidence. In July, Ferrovial sold its remaining 5.25% stake in Heathrow to Ardian and Saudi Arabia’s sovereign wealth fund. Macquarie Asset Management followed suit in June, acquiring stakes in London City, Bristol and Birmingham airports. Earlier in the year, Blackstone secured a £325 million deal for a 22% stake in AGS Airports, which operates Aberdeen, Glasgow and Southampton.
As passenger numbers climb and operational metrics improve, the UK’s aviation sector is not only recovering—it’s redefining its role as a cornerstone of national and regional economic growth. For business travellers, the message is clear: the skies are open, and the future is flying high.
