Qantas enables passengers to check in online starting 24 hours prior to their scheduled flight departure, offering a convenient way to select seats, manage baggage, and obtain boarding passes ahead of time. The exact cut-off time for online check-in depends on the flight type and destination. For domestic flights within Australia, online check-in typically closes between 30 and 60 minutes before departure. Specifically, flights with Qantas flight numbers 400 and above, as well as Jetstar-operated codeshare flights numbered 5000 to 5999, allow online check-in up until 30 minutes before takeoff. For domestic flights that connect to international flights, the deadline is usually 45 minutes prior to departure, while flights departing from international terminals within Australia have a 60-minute online check-in cut-off. When it comes to international flights, Business and First Class passengers can check in online until 60 minutes before their flight, whereas Economy and Premium Economy travelers have until 90 minutes prior to departure. Passengers who do not complete online check-in should plan to arrive at the airport early enough to check in at the counters. Qantas recommends arriving at least 45 minutes before domestic flights and two hours before international departures to ensure ample time for check-in, baggage drop, security screening, and immigration processes. Airport check-in desks generally close 30 to 60 minutes before departure, depending on the flight and location, so arriving late may result in denied boarding. Group bookings for domestic flights numbered 400 and above have a 60-minute online check-in cut-off. Using the Qantas mobile app can further streamline the process by allowing passengers to check in, access boarding passes, and receive real-time updates. While online check-in saves time and reduces airport queues, some passengers—such as those traveling with special baggage, minors, or requiring assistance—may need to check in at the airport regardless. Overall, Qantas provides flexible and efficient check-in options starting 24 hours before departure, with cut-off times tailored to flight type and class. Travelers should always confirm their specific check-in deadlines through their booking details or Qantas customer service to ensure a smooth and stress-free start to their journey.
