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.
