Hurricane Irma is grounding travelers as far away as London and Doha, CNBC reported Sunday.
Airlines on four continents canceled flights to and from Florida, as the massive hurricane lashed the Florida Keys on Sunday morning.
Carriers have called off at least 10,700 flights β including 7,400 in Florida alone β because of Irma, according to plane tracker Flight Aware. That number is set to rise as Irma heads north near Atlanta, a Delta hub and the world's busiest airport.
