Your Flight is Canceled!

As I saw people waiting impatiently or sleeping at airports around the country early this week, following the Northeast's blizzard, I wondered why anyone would have thought they had the slghtest chance to fly. It was then that I realized that for the average person there really is no way to know if your flight is going to be delayed or canceled.

If you go to the Federal Aviation Administration's airport status site at fly.faa.gov, you'll see flight delays in real-time but you won't necessarily see flight cancellations. Oftentimes the flight delays may be small, but if flights are being canceled there will be fewer delays.

I've seen airports closed down because of weather - all flights canceled - and, officially, the airport reporting there were no delays. Sure. There weren't any flights to delay!

After spending several years working with airlines, helping them manage their fleets with weather forecasts, I know it is fairly easy to predict when flights will be delayed. And when the probability of delays goes up, the probability of cancellations increases.

We rank the probability of flight delays for the next 4 days at 50 airports around the country (and if you are an annual subscriber to the service you can request that we add one or two more). We look at snow, fog, freezing rain, high wind, thunderstorms and other factors, then assign a probability for delays.

We want it to be simple to use so our range is from 0=no weather-related delays to 10=100% chance of delays. A rank of 1-4 usually means you'll run into minor delays of up to an hour. At 5-7 you may have delays of more than an hour and run the risk of a couple of canceled flights. At 8-9 you can expect delays of at least 3 hours and there will undoubtedly be cancellations. And a 10 means we expect widespread cancellations.

Each day is broken down into the AM (5am to 9am) and PM (3pm to 7pm) hub times. We cannot guarantee your particular flight will be delayed or canceled, but we lay out the odds. For example, I'd bring some extra reading material when an airport is ranked at a 4. Bring extra reading material and extra cash for food when an airport is ranked at a 7.

For an 8 or 9 you might want to bring a pillow, consider rearranging our itinerary or do yoga so you don't get angry at the fine folks at the ticket counter for something out of their control.

Finally, there's the 10 - the magic number assigned to BOS, LGA, EWR and JFK this past weekend. At a 10 you might want to book a room for an extra night. Those 10s are rare, but if you know two, three or four days ahead, you can explore your options before spending a day or two in the Green Concourse all smelly, exhausted and grumpy.

At least we do offer a tool so you can better play the odds and be more understanding when you call the customer service agent to confirm your flight status. Check it out at OrrWeather.com or click here.
