LONDON — Heathrow Airport said on Tuesday that it would limit the number of passengers until mid-September, citing staff shortages that have led to long lines, delays, lost luggage and last-minute flight cancellations.
In an open letter to passengers, Heathrow chief executive John Holland-Kaye called on airlines to stop selling new tickets as critical functions in the airport have been significantly constrained.
“We recognize that this will mean some summer journeys will either be moved to another day, another airport or be canceled, and we apologize to those whose travel plans are affected,” he said. In recent weeks, there have been periods when service had dropped to a level that was “not acceptable,” he said.
Mr. Holland-Kaye said the airport could handle no more than 100,000 departures each day, slightly less than the 104,000 he estimated it would be expected to serve on average. He asked airlines to limit the number of tickets they sell to bring numbers back under the 100,000 cap.
When asked how Heathrow would enforce the capacity limit, a spokeswoman for the airport, Hannah Smith, said that this would be managed by an independent coordinator, Airport Coordination Limited. “Airlines have discretion as to how to apply the limits in their individual schedules,” she said.
One of Britain’s largest carriers, Virgin Atlantic, said in a statement that it stood ready to deliver its full schedule this summer.
“However, we support proactive measures being taken by Heathrow to reduce disruption, as long as action proposed does not disproportionately impact home carriers at the airport,” the airline said. “Action should be based on thorough analysis showing the most effective measures to improve the situation and keep customers moving.”
Summer travel in Europe has been marred by chaos at airports as airlines have struggled to keep up with surging numbers of passengers, eager to travel after pandemic lockdowns, and staffing shortages. Last week, Scandinavian airline SAS filed for bankruptcy protection after its pilots went on strike. There have also been walkouts by airport and airline staff across Europe, amid frustration with long hours and low pay that has not kept up with rising inflation.
Other airports have introduced similar measures. Last month, Schiphol Airport in Amsterdam introduced a capacity cap, citing a shortage of security employees and demand for air travel far exceeding expectations, and London’s Gatwick Airport last month also said it would reduce flights for July and August. British Airways said it would be operating on a reduced schedule by 11 percent through October.
Mr. Holland-Kaye said that Heathrow had started recruiting in November, in anticipation of high demand for summer travel, but that some key roles were still understaffed, including ground handlers, who airlines contract to load and unload bags, turn around aircraft and provide check-in services to passengers.
