All Boeing 737 Max airplanes are currently grounded, and we don't know when they'll be allowed to fly again. In the meantime, United Airlines has canceled more upcoming flights involving the planes.
United initially said flights would be canceled until July, but now the airline has extended that to August. This puts United on the same timeline as fellow U.S. carriers American and Southwest. The airline is expected to cancel around 2,400 flights between June and July.
In a statement, United said, "We won't put our customers and employees on that plane until regulators make their own independent assessment that it is safe to do so."
The Boeing 737 Max plane was grounded in March after software malfunctions led to two separate crashes in a span of months. The crashes killed 346 passengers and crew members.
Earlier this week, the acting administrator of the FAA said there's not currently a timeline for recertifying the 737 Max.
