Is there a site to see how many flights arrive are arriving airport at certain times?

FlightAware does this.

Ummm. Homeland Security would like a chat with you…


As someone said FlightAware is awesome. When I lived by the Addison,Tx airport we used it when we sat and drank outside while watching planes land. It’s great when traveling too. It will normally update gate changes and early/late arrivals before the airline does.

There are often feeds probably pulled from Flightaware's sources on individual airport websites, too.

However, I hit the Flightaware app, bookmark the flight the person that I'm meeting is on. I know when they're boarding, when they get delayed, if their gate/concourse changes, etc. It tells you their planned flight speed, altitude, how they intend to route, speed changes, etc., it's great.

I'm stunned at the number of people in my extended ex-family that aren't sure when they're leaving, where they're sitting, when they're landing, what flights they're on, and even WHICH AIRLINE THEY'RE FLYING. You're either in the same situation or she's cheating on you.
