Our Review of Seattle Tacoma Airport

All the information featured on this page was compiled and written by David Enrich, a renowned expert in aviation and airport guides since 1999.

At Plan Your Trips, we have analyzed hundreds of airports around the world, gaining a clear understanding of what users expect when visiting an airport. With this know-how, we have created this guide, placing passengers at the forefront of everything, aiming to simplify and enhance the airport experience.

In this guide, our goal is to present information in a manner that is both quick and reliable. Recognizing that passengers often have limited time and may be in a hurry, we strive to ensure that they do not waste time unnecessarily.

Another key focus of our guide is to highlight the strengths of the airport and also the weaknesses, and in some cases, offer recommendations to travelers. In alignment with this approach, we provide users with aggregated information on delays and on-time performance, analyzing both airlines and individual flights.

How we calculate On Time Performance

On various pages of our website, you will encounter a metric widely utilized in aviation and other forms of transportation known as OTP (On Time Performance). We believe that providing this metric assists passengers in planning their trips and exploring alternatives before purchasing their flight tickets.

We calculate the On Time Performance for all flights and airlines, when we have enough data to do so. In certain instances, it may not be feasible to accurately compute the On-Time Performance for a specific flight or airline due to inadequate or non-representative data, which could result in misleading conclusions.

Our calculation of On Time Performance and delay information solely relies on arrival times. This approach is chosen over calculating departure delays, as we consider arrival punctuality to be of primary concern to passengers.

The On Time Performance displayed on our website is calculated as follows:

On Time: Flights that arrive within 15 minutes of their scheduled arrival time, or earlier. In the absence of data for a specific flight, we assume the flight arrives on time, to avoid penalizing airlines for data unavailability.
Moderate Delay: Flights that arrive with a delay of 15 to 30 minutes.
Significant Delay: Flights that arrive with a delay of 30 to 60 minutes.
Major Delay: Flights that arrive with a delay exceeding 60 minutes.
Average Delay: The average delay is calculated by considering flights that arrive early as having a delay of 0 minutes. Early arrivals do not contribute to reducing the average delay calculation
