The capacity of the airport will be limited to 100,000 departing passengers a day through October.

In July, the airport imposed a cap due to staff shortages that resulted in canceled flights. The limit had been set to last through September. The company said that the restrictions could be lifted earlier if operations improved before October.

The cap has led to better punctuality, according to the statement. The statement said that by balancing passenger demand with available resources, we are able to operate a safe airport environment.

In the four weeks before the cap, 40 percent of flights were delayed and 2% were canceled, according to data from FlightAware. In the four weeks after the cap was put in, the average rate of delay dropped to 32% and the average rate of cancellation to 1.3 percent.

"Heathrow simply doesn't have enough workers to maintain its operations and that's why the capacity limit has been extended." She said that the hourly workers can bring an operation to a halt.

High demand from passengers caused travel to be chaotic. That resulted in lost luggage and canceled flights. The capacity limit for departing passengers has been extended by the airport.

Henry Harteveldt said the capacity limits have been a mixed bag for summer travelers. He said that travelers don't have the choice of flights that they otherwise would.

He hopes the seat cap ends before October. I think it's better for everyone if it ends soon.
