Airlines, including American and United, recommend passengers to arrive at the airport two hours before a domestic flight and three hours before an international flight. Similarly, Austin airport advises passengers to arrive at least two and a half hours early for domestic flights and three hours for international ones, even though its check-in desks are conveniently located right next to security, and there are no airport trains or long walks. The question arises, why are passengers told to arrive so early?
There are several plausible reasons behind this. One is that airport personnel need ample time to check-in everyone and load luggage onto the plane. An increase in passengers may cause check-in counters, security checks, and boarding gates to be busier than usual, extending the waiting time.
Airlines might also want to avoid the possibility of passengers missing their flights, and avoiding the hassle and cost of rebooking, which may negatively affect their reputations. Such situations are unfair to the passengers who did plan ahead and arrived on time. Arriving early also enables passengers to go through passport control and customs more flexibly and without rushing.
Airlines face the risk of flight delays due to late-arriving aircraft. However, the flight schedule is built to minimize such potential for delay. If a late-arriving aircraft causes a delay early in the day, the airline uses schedule buffering (extra time embedded in the schedule) to recover, so by the end of the day, the flights are back on schedule.
Border control agencies also have substantial influence over how long passengers need to wait at the airport before their flight. They need time to screen passengers properly. Hence, they encourage early arrival to ensure enough time for security procedures.
Lastly, the time quoted to passengers also takes into account potential queues at shops and restaurants at the airport. It is beneficial for airports to have passengers spending time, and therefore money, at the premises. More time spent by passengers means more money spent at airport businesses.
To be on the safe side, it is recommended that passengers adhere to the suggested arrival times to ensure a smooth and stress-free travel experience. Though it might seem excessive to some, the extra time gives a buffer for any unexpected occurrences and allows for a more relaxed start to your journey. It’s always better to be safe than sorry when it comes to air travel.
