Congressional negotiators have agreed on a $105 billion bill designed to improve the safety of air travel after a series of close calls between planes at the nation’s airports.

House and Senate lawmakers said Monday that the bill will increase the number of air traffic controllers and require the Federal Aviation Administration to use new technology designed to prevent collisions between planes on the ground. They agreed to prohibit airlines from charging extra for families to sit together but left out other consumer protections proposed by the Biden administration.
