UA 3678, EWR-SAT, divert to IND on 2/19

Wed Feb 19, 2020 7:40 pm

This is the third time in several months that this flight has diverted while enroute to SAT. On each of those occasions, the weather and operations at SAT were normal. Does anyone know why? Seems too often to be a coincidence.

Thanks

Maybe winds? 4 hours on an E170 is probably pushing it in terms of range. Seems like overkill. Does this route not have enough demand to warrant mainline service?

Likely a fuel diversion. E170 should have the legs to make it, but the jetstream is strong and wide today - 140+ mph winds all the way from EWR to SAT. Turns a 1600 mile trip into a 2100 mile trip - throw in reserve fuel and alternative airport and you're pretty much at the limits of what the plane can do.

IND seems to be less than halfway to SAT from EWR,

wonder why not divert to a closer airport if fuel related?

"halfway" is arbitrary. It really just needs to be close enough to SAT to make the trip to SAT not a big deal.

IND is probably chosen because it's Republic's headquarters and a maintenance and crew base.

On 2/13 it made a tech stop in BNA instead of IND. stopping in BNA does reduce the total trip length compared to IND but I guess Republic decided that the benefits of stopping at a crew and mx base outweighed the extra miles flown.

For some reason, I cannot see these diversions on FR24. Anyone know why?

Well closer airports are being hit by weather. Also, IND is a crew base for Republic, could be a crew change required and IND is also an easy airport to get in and out of.

The winds aloft on the route today are averaging 94kts at 30,000ft, no fun!

Republic will favor IND/CMH/PIT/SDF when necessary. (Not anecdotal). If they need to top up, that's where they're heading.
Good goes around!

It probably could support mainline.......but is out of Domestic aircraft until the MAX is back in the air.

One would think a city the size of San Antonio could support an aircraft larger than an E170 from EWR. It continues to astound me how a large city like San Antonio has such limited air service. Over the years, many airlines have attempted to expand service to SAT but it never seems to be successful. Meanwhile, nearby AUS continues its trend of exponential growth.

Right. Which is probably the case. But the fact that UA decided that the E170 was enough and did not remove mainline from a closer city-pair probably does show that mainline may not be a priority or something that is critical.

Currently, United has two daily flights EWR-SAT. One operates mainline and the other is a regional jet.

American and Delta both operate mainline nonstops to SAT-Kennedy.

And that makes sense. Those are mostly bases and all have a fair amount of excess gate space and, likely, staff time that makes a gas and go quicker. On a UA flight, a quick stop at BNA can turn into a 90 minute affair if things are gummed up.

Because UA3678 is not scheduled to fly IND-SAT, BNA-SAT, or CMH-SAT. Try YX3678 instead.

On the contrary, the weather is fairly bad in South/Central Texas. It’s well below the minimums that mandate filing an alternate and when AUS is below alternate minimus - like today - you’re either leaving behind passengers or making a fuel stop.

They have to carry enough fuel to make EWR-SAT but also to go missed approach and then fly to either DFW or IAH.

E170 should have the legs to do it. I'm surprised EWR-SAT is operated with that aircraft as it used to be on 737s for years and at one point (briefly) in 2013-2014 a 757.

I live in AUS. Today it's Low Ceilings, chilly, and some rain but nothing major. The weather has been so up and down this year so far it's insane. It was 80 three days ago and barely broke 50 today and had some big league late night Thunderstorms last week when temps were in the low 40s. Oh, and we actually had snow that stuck to the ground 1.5 weeks ago and it was 70 two days later. A little too "Denver-ey" weather wise for my taste lately.

Yep. Exactly. If the crap hits the fan, they can re-crew it, too. I've definitely seen that at IND before. In fact, I've seen a lot happen in IND with YX where the base came in awfully handy. lol
