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 runways.

Lawmakers agreed to prohibit airlines from charging extra for families to sit together, and they tripled maximum fines for airlines that violate consumer laws. However, they left out other consumer protections proposed by the Biden administration.

The bill was negotiated by Republicans and Democrats who lead the House and Senate committees overseeing the FAA, which has been under scrutiny since it approved Boeing jets that were quickly involved in two deadly crashes in 2018 and 2019. The legislation will govern FAA operations for the next five years.
