WASHINGTON, March 12 (Reuters) - Chicago urged the

Federal Aviation Administration on Thursday not to cut daily

flights at the city's O'Hare International Airport below 2,800

per day, saying it would be unwarranted "and would lead to

significant disruption to the National Airspace System."

The FAA on Feb. 27 proposed a 2,800 daily flight limit for

summer flights, down from the 3,080 daily operations announced

for the summer but above last summer's 2,680 daily flights.

Reuters reported on March 5 that the FAA told airlines it

wants to ​limit flights to around 2,500 per day, but that number

remains under ⁠discussion.
