Recommended arrival time
The recommended arrival time at Buffalo Niagara International Airport (BUF) can vary depending on several factors, including the time of day, holiday travel periods, and individual airline requirements. Generally, it is advised to arrive at the airport early enough to allow for a smooth and stress-free travel experience.
During peak hours, such as early morning flights and holiday travel, security lines tend to be longer. To avoid lengthy queues, passengers are advised to arrive at the airport at least 90 minutes to two hours before their scheduled departure. This buffer allows adequate time for check-in, security screening, and travel to the departure gate.

Additionally, real-time security wait times may be available on the airport's website, helping travellers make more informed decisions about their arrival time.
