Very Roundabout Route For AA's BOS-SAN

Thu Jul 19, 2012 1:34 am

Hey all,

I know that the US northeast was a total mess today with t-storms. I was looking at some random flights, and noticed this. I would guess this route was to avoid some storms, but this is VERY out of the way:

You mean JFK-SAN, yes?

Well, fortunately it's not a 738 and it's a 763.

Depends on the upper winds just how "out of the way" it really was. Just by taking a quick look, though, you can see they've avoided a number of storms, and their filed time is only 20 minutes longer than the weekly average.

AA would rather add some distance to the route and get around the storms in Kentucky//West Virginia and the Chicago area (as well as other storms), rather than wasting time flying through the storm (not to mention possible severe turbulence if they chose to fly through the storm). It's easier and safer just to fly around storms and spend a little more time in the air.

We recently did a similar routing on a similar city pairing BDL-LAS. We utilized a best wind route, and even though it was 200nm farther than a direct routing, it was 35 minutes faster.

It looks very similar to the July 13 track for that flight.


A few years ago we flew a BDL-DFW trip on AA. It took an hour longer than the normal flight, and we were happy because the departure from BDL was delayed six hours due to storms in both the northeast and across the south/ center of the country.

When I got home, I checked the track on FlightAware. We had flown from BDL to Toronto - across to Minneapolis over South Dakota and southwest to the corner of Colorado, Kansas and Nebraska - then south to near Lubbock and then to DFW.

Throughout the flight we could see huge thunderstorms with tops much higher than we flew to the south, and eventually to the east. DFW was a mess with late, delayed and cancelled flights.

I flew through a thunderstorm day like that back in 1974 - and it was the roughest flight I've ever been own. Always happy to fly out of the way to avoid such weather.

Normally, AA's MIA-ORD flights head right over ATL and southwest Indiana and then up to ORD. I was on an AA MIA-ORD flight once that took an hour longer due to thunderstorms over ATL, so we went over TPA, MEM, STL and eastern Iowa and came in from the west.

That's not bad at all. I did a JFK-SAN flight a few years ago, went all the way up along the US/Canada border due to nasty weather in the NE and Ohio Valley, then we went south....WAAAAY south, heading over the US/Mexico boarder somewhere around Western Texas due to some huge storm system over most of the western 1/3 of the US that was swooping in from Canada. 6 hours, 17 minutes. I wanted to bang my head on the sidewall until I blacked out LOL.

That's not too atypical. I fly LAX/SFO-JFK r/t about a dozen times a year, its not unusual to fly into Minnesota and then cut down around South Dakota like they did. On at least 1 occasion I can remember, we didn't cut south until almost Idaho.

As an air traffic controller, I see crazy routes all the time. Airlines file seemly longer mileage routes all year long, even when there isn't a single storm in the entire country. The most beneficial route for any given flight depends on upper winds/storms/turbulence forecasts/mountain wave, etc. It especially varies during the winder when the jet stream often exceeds well over 100 mph out of the west. Airlines will fly most anywhere to avoid a 100+ mph headwind.

While this particular route looks to be for weather, no particular flight is guaranteed to fly the same route on different days, even if there are no storms in the flight path on either day.

FWIW. According to the FAA website (ATCSCC) which posts airport delay status, a lot of flight routes were closed that day in the NE area. I don't ever recall seeing that listed as reason for delays before. Usually they just list the weather issues that are affecting a particular airport.

While the jetstream appears north of the routing, the routing is closer to heading into the jetstream and would have more headwinds than a more southerly routing.

Would be a great flight if you purchased miles for first. You would have been able to enjoy it for a long period!      



I remember flying DFW-JFK on DL in first on mainline MD-80 and we had to go around storms which pushed us out to JAX then up over Chesapeake Bay then finally to JFK. I was one of 3 in First and I had the bulkhead to myself. Great cloud formations. We were just a little later than stated but still made my flight to FCO.
