Heathrow achieved 79% of pre-Covid 2019 levels in May as 5.3 million passengers used the London airport.
The volume was described as being in line with the hub’s revised traffic forecast.
Heathrow claimed that “close co-ordination and planning” with airport partners meant that passengers got away on their flights over the busy Jubilee half term.
“Check-in generally worked well, with more passengers checking in online and despite May being our busiest month since March 2020, 90% of passengers were through security in less than 10 minutes,” the airport said.
“No more flights were cancelled at short notice than on any normal day and Border Force performed well.”
However, Heathrow cautioned that resources remains tight, in line with other airports in the UK and Europe, “while we rebuild capacity from the pandemic”.
Terminal 4 is reopening tomorrow (Tuesday) as part of a long-standing ramp up plan, with 30 airlines moving in ahead of the summer peak.
“We are increasing our own security, engineering and services teams, and supporting other employers across the airport with their recruitment,” Heathrow added.
“We are working closely with airlines and handlers to match supply and demand. This has made the difference at Heathrow in being able to get passengers away over Easter and the Jubilee half term and is now being adopted by other major hubs in Europe.
“Recent criticism of service levels across the sector demonstrates that our plan to maintain high levels of passenger service during the [current] H7 regulatory period is the right one for consumers, and that the last thing passengers want is a cut price plan that leads to the cancelled holidays, stress and ‘hassle’ seen at other airports.
“We urge the Civil Aviation Authority to protect service and resilience levels, incentivise investment and maintain affordable private financing, all of which can be achieved for less than the equivalent of a 2% increase in ticket prices.”
Heathrow chief executive John Holland-Kaye said: “I’m immensely proud of the way my team has worked with airlines and other partners to ensure passengers got away during the Jubilee half term.
“We continue to make good progress with our plans to ramp up capacity and are working closely with airlines and government to keep supply and demand in balance as we grow, so that passengers can travel through Heathrow this summer with confidence.
“We now need a regulatory settlement from the CAA that protects service and resilience levels, incentivises investment and maintains affordable private financing. Failure to invest risks degrading passenger experience at a time when it has never been more important for operations to ramp up smoothly.”
