How It Works

According to the U.S. Department of Transportation, approximately 75 percent of all flight delays are due to inclement weather. *

Everybody has a story about being delayed for an important meeting, sales pitch, wedding, graduation, kid’s event or just getting home after a long week on the road. Being stuck in an airport or city can be extremely frustrating and expensive. Since airlines do not reimburse for weather-related delays, the average delay can cost travelers hundreds of dollars in lost time and out of pocket expenses.

KnowDelay’s mission is to help travelers avoid weather-related flight delays.

We predict flight delays and notify travelers up to 3 days in advance of their trip, while there’s still time to find alternatives or change plans.

KnowDelay’s team of experts has been working for years to develop a predictive engine that takes into account weather and airport performance to be able to score your itinerary. While KnowDelay cannot predict every weather event, you have the comfort that we are working 24hrs-a-day to cover your flight and notify you if there is a concern.

Let KnowDelay track your flight, find alternatives, and gain an added level of comfort through our notifications.

If you are booking within three days of travel, why not let KnowDelay score your itinerary before booking to ensure you make the right choice and arrive on time!!!

HOW WE DO IT

KnowDelay was founded by airline pilots and technologists who recognized how complex weather and airline operations can be. We incorporate the policies and practices used every day as airline pilots – such as closely monitoring weather and developing alternate plans – into the KnowDelay system. We developed the service to help travelers avoid those frustrating weather-related flight delays.

We’ve created a unique weather “recipe” that uses a variety of different weather models to estimate the impact and duration of a weather event and then translates that weather impact into predicted airport delays. We also look at weather across a large radius around the airport, since delays can be caused by weather that’s far from the airport. That’s all accounted for in our modeling of the 35 most delay-prone airports in the United States.

We provide our predictions using an easy-to understand three-color traffic light system: Red, Yellow, and Green, showing the likelihood of a 30-minute or greater delay.

Our accurate model has saved our customers time and money by allowing them to avoid delays. But we don’t always get it right. Just like in the airline world, we don’t want to be caught flat-footed so we over-predict bad weather. Like an airline pilot, you’ll never surprised and you’ll have alternatives. Use KnowDelay. No Surprise. KnowDelay.
