London's Heathrow Airport caps daily passenger numbers to quell summer travel chaos

London's Heathrow Airport is capping daily passenger numbers for the summer and telling airlines to stop selling tickets as it steps up efforts to quell travel chaos caused by soaring travel demand and staff shortages. 

Britain's busiest airport said Tuesday that it's setting a limit of 100,000 passengers that it can handle each day through September 11. The restriction is likely to result in more canceled flights even after airlines already slashed thousands of flights from their summer schedules.
