Odd flight path for DL1631 (LAX-DCA) 6/19

Wed Jun 19, 2019 4:56 pm

I know winds and weather play a role in the route a flight takes, but today's DL1631 is going so far south it just seems odd. The route has it going down over southern Arizona, New Mexico, Texas, Louisiana, Mississippi, Alabama, up into south-central Georgia, then South Carolina, North Carolina and into Virginia. Looking at the past flights from this month they all go north.

What's taking this flight so far south today?

I can only speculate, but it’s likely due to the weather and associated sigmets in Indiana and Missouri, plus the turbulence forecast through those areas presently shows a fairly crappy ride.

The central Mississippi and Ohio river valley areas are basically closed due to ATC structures routings due to forecast TS this afternoon and evening.

Right on the front page here, you can see the thunderstorms and other weather in Missouri, Indiana, Kentucky, and Tennessee.

As a reference, United 2305, American 1339, and Alaska 1108 are doing the exact same thing.

The much earlier departed United 1135 went far north instead.

out of curiosity, what made you look at this particular flight path?

It's the MGM playbook route. If you check fly.faa.gov/ois there is a tab on the left for severe weather. Inside that there is a link for current re-routes. Cleveland, Kansas City, and Indy centers are too busy to handle all the deviations for weather so this playbook along with many others today was thrown out to spread out the traffic.

Airlines can request and sometimes are able to get exceptions to these required routings approved.

It seems rather obvious, does it not? The midwest has been getting pounded all spring.

Have a friend coming in on this flight and have an alert set on it. Saw it was going to be 30-mins delayed, so went to flightaware to see more details.

Taking a slightly more northerly route through north Texas, southern Oklahoma, Arkansas, Tennessee and up into Virginia would have been a clear path and more direct routing than the one it took.

Why would it have to go through the Midwest?

If the route you show is a snapshot of the route at the termination of the flight, you don't know where the weather was as if moved eastward. It appears this was not the only flight with this tracking. The midwest is basically anything from Oklahoma to Ohio, and all states north. They have been getting so much bad weather, the route makes sense.

So going through Tennessee was not really an option. Of course, now the chart on that front page has changed, and it looks a lot worse than it did when I looked at it earlier in the day.

If it was weather they were trying to avoid why did it fly right through a storm cell on the border of North Carolina and Virginia - https://flightaware.com/live/flight/DAL ... /KLAX/KDCA

Someone up thread already answered you but I'll reiterate it. On days where widespread weather affects large swaths of the US various ATC centers will declare that they cannot handle their normal traffic volume. When that happens ATC uses a "playbook" to route flights into ATC centers that are able to manage the traffic. Sometimes they are good routes but more often than not they are ridiculous circuitous routes that often go through more weather than they would have normally, just like the one you posted. In this instance your friend's flight had no choice but to fly that route as it was the only one ATC would allow today between those two airports.

Flight Aware just doesn’t have enough detail to show the true storm, it’s like NEXRAD which can’t be used fir storm avoidance. Pilots use weather radar.

I’ve taken a VERY southern route transcon to DC many many times. I’m not sure this is that interesting.

Oklahoma sure seems more Midwest than South to me too. Louisiana and Mississippi are in the South. But heck, if you read it in the Internet, that must be right then.

That may be true, but some storms are stronger than others. The storms in question have reached severe status so definitely not the kind of pattern to fly close to.

The storm over the Ohio River Valley has remained active since last night. There's a spot developing over Texas-Arkansas so it should be interesting seeing how flights are lined up through corridors between the weather systems. Looking at radar at the moment, there's a narrow path through MEM for flights departing the SE and heading north or west (trying to go through Texas will be quite a bumpy ride).

You would be surprised how the jet stream and or thunderstorms influence flight paths , highs and lows as well in regards to pressure systems . You gotta catch that wind the best you can

I don't know if I would necessarily trust FlightAware to give an accurate picture of the weather since I don't know when that radar shot was taken. The aviation weather website definitely didn't have that storm cell there when you made the initial post and I checked.
