There is a big problem between the United States and Venezuela. A former US president said the air above Venezuela is closed. Venezuela is very angry about this.
Because of this, Venezuela is doing two things. It will not accept some planes from the US. It also stopped six big airlines from flying there.
People in the US government are worried. They say only Congress can make big decisions like this, not a former president.
This problem is bad for airplanes and travel. It also makes the two countries angrier at each other.
