United Airlines gets a handle on cancelled flights: CEO Scott Kirby

Air travellers could breathe a little easier on Monday, as a break in stormy weather and lighter schedules a day before the July 4 holiday helped airlines keep more flights moving on time.

By late morning on the East Coast, fewer than 100 US flights had been cancelled, although 1,000 were late, according to FlightAware.

United Airlines, the worst-performing US carrier for more than a week, laid out steps to improve, including reducing flights at its hub airport in Newark, New Jersey.
