According to BBC reports, US airlines have cancelled dozens of flights into Mexico City over fears that volcanic ash from a rumbling volcano would affect their planes.
Delta and American airlines were among this cancelling more than 40 flights into the capital on Thursday.
The Popocatepetl volcano has been rumbling all year, but began spewing ash and steam earlier this week.
Airport authorities have kept the runway open and say that the volcano poses no risk to flights.
“There is a very thin presence of ash, which does not harm operations or affect equipment,” an unnamed airport spokesman told AFP news agency.
Mexico City airport has said that US Airways, Delta, United, American and Alaskan Airlines had cancelled flights as a precaution. Routes affected by the cancellations were flights to Houston, Dallas, Denver, phoenix, Chicago and Los Angeles.
Mexican airlines are continuing to fly into the airport as scheduled.
Mexican authorities have established a 7-mile (11km) no-go zone around the volcano, which lies 40 miles south-east of the Mexico City airport.
Popocatepetl volcano has been spewing ash and a fountain of hot rock since May, and the alert level is currently set one notch below evacuation level.
On Thursday several tremors were reported around the volcano, but officials said they had no immediate plans to raise the alert level.
