FlightAware's MiseryMap is pretty cool too https://www.flightaware.com/miserymap/

Okay that's neat. It was interesting watching how the misery changes as the storms roll through watching something like DAL which is easy to see the effects. The cascade effect on cities without storms reminds me of how auto traffic slow downs from an accident continue to linger even though the blockage has cleared.

The UX is giving me misery.

Most of the time the red fills in counter-clockwise. Until it is over 50%, then the red fills in clockwise.

Lots of the map circles actually represent MULTIPLE airports. But they still "represent" them with a three letter code. Sometimes by the largest airport (ORD, SFO), sometimes by a non-airport code (NYC), and sometimes by the second largest (DFW is larger that DAL).

Someone's pet project needs some more love.

Just as a fun fact, there are IATA airport codes that designate cities instead of airport for purposes like this. NYC is one of them. So is YTO (Toronto) or CHI (Chicago, which should probably replace ORD).

LON = London. Heathrow, Gatwick, Stansted, Luton, City, Southend.

A lot of these are just airport code quirks, like LND being every airport in London. CGPGrey has a great video on the topic

Didnt expect this to trend on HN. I used to travel every week for work and learned to used this and fly.faa.gov/ois to find out how long ground stops will be during delays for years.

While I'm on this soapbox: ExpertFlyer. If you travel once per month or more, it is ABSOLUTELY worth the $10/mo. They provide a lot of info straight from GDSes, somehow. Invaluable for rebooking and seat changes.

I’ve been using Flighty for this. This sort of tool is life changing. Today in DFW, it told me about my plane’s delay at least 15 to 20 minutes before the gate agent knew!

Flighty is also just delightfully made. If any of the devs encounter this: thanks!

That faa.gov url won't open. Can you share the correct link?

by pogue

To be precise, both links are "correct": one is non-functional from your device.

If you are delayed, get this tool up. It is a huge informational advantage over the data the airline will give you and provides excellent help making a decision on seeking a different mode of transportation, giving up and going home, taking an inferior seat on a different airline etc...

Use this all the time for flying, it's fantastic. Great to know you'll be delayed before they even make the decision.

Highly recommend the 'Map View' tab and the 'Weather' tab (especially with Cities + Fronts enabled).

When I looked SFO, DEN, LAS, and EWR were all delayed due to weather. Do busier airports end up on this list more for some reason, or is it just really bad luck today?

It's a day off for ORD, DFW, ATL, and MIA.

YYC airport code is for Calgary, Canada. Why is on the US .gov site is there something I missed

by pavelstoev

Plenty of US domestic flights leave YYC every day. You clear US customs and immigration in Canada before getting on the plane so you can land at any airport in the entire country, not just international ones.

Is something going on? Why is BOS closed?

by VectorLock

4/25/2025 at 12:07:31 AM

This is the note:

> Closed TO NON SKED TRANSIENT GA ACFT EXC PPR 617-561-2500

Which translates to “closed to non-scheduled transient general aviation aircraft, except those with prior permission from calling 617-561-2500”

They just don’t want me flying my Skyhawk in there at 90kts on final, at least without calling them first so they can get some cathartic tongue lashing in before giving me permission.

by rogerrogerr

It’s closed to unscheduled transient flights, which is normal when an airport gets busy/backed up.
