Given how easy is it has been to upgrade SFO-BNE and BNE-SFO, I’m sure there were a few itineraries that were routing via BNE to/from MEL/SYD on Virgin (or even Qantas since United sells that option as well).

UA892 ICN-SFO 789 on 2/14 was cancelled due to maintenance

UA35 SFO-KIX 788 cancelled maintenance (return 34 cancelled)
UA53 ZRH-IAD 763 cancelled maintenance
UA96 SFO-BNE 788 cancelled maintenance (return 97 cancelled)

UA143 DEN-NRT 789 on 2/16 is (again) significantly delayed. This time by 7 hours. Due to this today's flight UA142 is cancelled.

UA23 EWR-DUB 763 on 2/16 was delayed by 8 hours, then cancelled altogether due to maintenance. UA22 return cancelled.
UA28 SIN-SFO 789 diverted to GUM. Scheduled to do GUM to HNL then HNL to SFO but HNL to SFO segment was "cancelled". That segment should be flown as UA3935.
UA34 KIX-SFO 788 cancelled maintenance
UA142 NRT-DEN 789 cancelled due to outbound flight delay
UA938 ORD-LHR 763 cancelled maintenance
UA986 CDG-ORD 763 cancelled maintenance

Yikes. I was supposed to be on that. So glad for my change in plans now. Any idea why the diversion? SIN has been being hit pretty roughly lately

Of course. What would be a better method for picking which flight to cancel other than the one that has the smallest negative impact on the operation?

Flights that could otherwise operate are not cancelled because of light loads. When you have to cancel a flight then you pick the flight which has the smallest negative impact which is often the one that has a light, if not the lightest, load. It depends on more than just that one leg, though, as a cancellation affects other flights downline.

Totally get this analysis and don't disagree -- but why it happens is my issue. This perspective is very US focused and completely represents the US laws regarding air travel -- that's why it is different in the EU (and tbh should be in the US). Because at the end of the day the US airlines do what is best for revenue management (not total number of pax affected lol) -- because that is what the law in the US allows. As someone that lived in a non-hub (ROC) for 30 years my flights were often cancelled (to be clear this is not a UA thing) so much because they needed a plane for "more important / higher revenue" routes - and I was left to find my own way...

When there is no financial penalty for cancelling a flight why would we expect US airlines to do anything else? They choose the best way to make the most money which is what we wold expect them to do absent any consequences -- but in the EU it's different. Better / worse -- that's debatable -- but to associate US airlines doing the best thing for the most people is a bridge too far for me.... I am sure that the people that fly the planes / work the planes DO care about that -- their management -- not so much.....

Not following your assertion; the OP noted that when an airframe goes out of service and something needs to cancel that United often chooses the flight with the least impact to customers. Are you implying the look at the fares paid and not the number of pax when they decide what to cancel?

bmwe92fan

Yes - I am 100% implying they look at the cost / profit to operate versus number of pax affected -- but note that I wasn't making this a UA specific thing.... There is ZERO penalty in the US for this which is why it is common -- in the EU the financial math is different -- so the IRROPS handling is different as well... It's not a hard concept to understand - its just business....

As a GS impacted my multiple cancellations last year on C and D fares I’d disagree. I really don’t think they financially model every cancellation to optimize profit. Perhaps their models are that sophisticated, but I’d be surprised. It’s much easier to look at number of people impacted than model for profit per individual pax, some goodwill X factor based on number of elites / status and other variables.

that said, I’d be impressed if they’ve gone there…but don’t appreciate the “it’s not hard to understand” - I read your reply multiple times and legit was asking because I didn’t know if you were suggesting that or not

bmwe92fan

Sorry if I offended -- wasn't my intent at all -- US airlines revenue management algorithms during IRROPS are much more sophisticated than you think -- I know because I helped to write them many years ago -- and then worked in the industry for many years.... It's been a while -- and they could have changed in the past 10 years -- but I doubt it....

ironmanjt

No worries - and in that case I stand corrected. Impressed to see they manage it with this level of detail. Given their passenger facing IT in many cases I wouldn’t have expected it.

if anything, I’d expect like most industries they’ve gotten more sophisticated in the last 10 years - and AI will likely increase that exponentially going forward

bmwe92fan

The airline business is like any other business -- you have costs to operate and the revenue associated with those costs -- when there is an issue (IRROPS) the airline will optimize for revenue -- not the number of people -- it's really not that difficult a business decision.... Sorry if my wording made it imply something else -- and as I said it's been a while -- but I doubt Kirby changed these types of things lol.

UA97 BNE-SFO 788 cancelled maintenance
UA958 LHR-ORD 763 cancelled maintenance

Why so many BNE getting cancelled?

WineCountryUA

No specific knowledge but ULH flights are cancelled more frequently as the amount of time delay they can handle is limited before the crew times out. Other factors that increase cancellation is limited time window for arrival or departure due to curfews or other time restrictions.
