The main purpose of this legislation is to improve communication between airlines and passengers regarding flight delays. It aims to ensure that passengers are kept informed about the status of their flights, particularly when there are significant delays. Key provisions of the legislation require airlines to notify passengers whenever a flight is delayed by 15 minutes or more. Airlines must provide updates at least every 15 minutes until the delay is resolved. Notifications must be sent via email or text message and should include the new estimated times for departure and arrival.
