Facing a shortage of air traffic controllers, data shows flight delays are on the rise as the government shutdown drags on. It's a trend that is expected to continue as federal officials plan to cut travel by 10% at 40 airports starting Friday.

Nearly a quarter of flights arrived late into 16 of America's busiest airports in the week after air traffic controllers missed their first paycheck on Oct. 28, according to a CBS News analysis of data from aviation company Cirium. That's compared with 18% of flights arriving late in September.

Fifteen of those airports are included on a list obtained by CBS News of potential airports that will be affected by the 10% cut in air traffic. Some major airports, including those in Las Vegas and Charlotte, were not included in the data.
