How many minutes prior to departure do flight attendants board at a hub/line station?

Flight attendants are required to board at a hub or line station 30 minutes prior to departure. This timing is essential for several reasons. Firstly, this allows the crew to participate in pre-flight briefings, where critical information about the flight, potential challenges, and passenger details are discussed. Secondly, boarding 30 minutes ahead of departure provides adequate time for safety checks and ensuring that all equipment is ready and in compliance with safety regulations. Additionally, it allows the flight attendants to greet passengers, help with seating arrangements, and settle any last-minute issues that may arise before takeoff. This practice ensures an organized and efficient boarding process, contributing to overall flight safety and service quality.
