## Takeaways

1. Storm location can determine which routes remain usable.
2. FAA traffic limits can account for worst-case weather.
3. Simulations estimate 50–75% fewer Denver summer weather delays.

## About this segment

United's AI simulations suggest rerouting around pop-up storms could cut Denver's summer weather delays by 50–75%. Scott Kirby says FAA rules currently impose worst-case traffic limits.

## Transcript

Transcribed by machine (Whisper) from the episode’s audio, so a word may be off here and there.

[19:49](https://realalpha.app/v/3Lc0xfW4r9Q/?t=1189) Now, this one, we're going to have to get the FAA to help us. But we started running simulations with AI from Denver in the summer. In Denver, there's a lot of pop-up thunderstorms that happen around the airport. Denver is really... You're a Bet Noir. Well, no, it's not. It's actually easier than the other. Newark is the hardest. My two options are Chicago and Denver. It's just a roll of the dice.

[20:10](https://realalpha.app/v/3Lc0xfW4r9Q/?t=1210) Yeah, yeah, yeah. But this will help, like Denver especially, because Denver and the— winter storms are actually pretty easy. You know what's happening. Pop-up winter storms are what's hard. The reason is because if a lightning strikes within three miles of the airport, the ramp closes for 30 minutes. People are allowed to be outside. Which one is dumb. Like if if a storm is moving from the east to the west and you have or from the west to the east, which is what happens from the west to the east and it happens west of the airport, you should probably close it.

[20:38](https://realalpha.app/v/3Lc0xfW4r9Q/?t=1238) But if the storm is moving west to east and it happens three miles to the east of the airport, you don't need to close it. So anyway, using AI. So what will happen is there'll be a forecast in the afternoon for there's going to be thunderstorms. And so the FAA just takes the worst case. We don't know where the thunderstorm will be. They close, they limit all the quarter posts, and they just pull down the amount of traffic that's going through the airport proactively, take the worst case.

[21:00](https://realalpha.app/v/3Lc0xfW4r9Q/?t=1260) But when you look at the data, like, well, sometimes the weather is to the southeast, but in most cases, you can use different arrival routes and departure routes, but you can keep the airport running. Because there is nothing around Denver Airport, so you have lots of space to work. Yeah, and you can keep the airport running. We can probably reduce 50% to 75% of the weather-impacted delays in Denver in the summer by using this kind of technology.

[21:21](https://realalpha.app/v/3Lc0xfW4r9Q/?t=1281) I mean, it's just transformational because that's my point about expectation management. Instead of just saying, oh, weather, like my previous employer, I had told people, the operations team, anyone that says the word weather in my presence is going to get fired because I do not want to use weather as an excuse. I know weather happens. I know we have to, you know, we're going to be safe. We're never going to do anything that's unsafe.

[21:44](https://realalpha.app/v/3Lc0xfW4r9Q/?t=1304) Weather does happen. But our job is to figure out how to minimize the impact of weather, and you can't use weather as an excuse. So that's my expectations management point. I want to have our culture be, we find ways to overcome the challenges, to try to manage your expectations. We try to set high expectations and try to meet them. But we do communicate with you.
