Heathrow Airport has introduced a cap on passenger numbers over the summer as the aviation sector struggles to cope with increased travel demand. No more than 100,000 daily passengers will be able to depart from July 12 until September 11, the west London airport announced.
Airlines planned to operate flights with a daily capacity averaging 104,000 seats over that period, according to Heathrow. The UK's busiest airport believed this would be more than the number of daily passengers that could be processed in an acceptable manner without impacting service levels.
It has since ordered airlines to stop selling summer tickets to limit the disruption to passengers.
