781 maintenance disruptions

UA240 EWR-LAX was cancelled yesterday and today due to "maintenance-related schedule disruptions" (same for the inbound flight for the a/c which is typically UA1882 LAX-EWR)

1) Is there a broader maintenance issue with the 781s? Looks like they've been taking delivery of about 1/month since last November.

2) Also curious that UA didn't sub a 772 or 752 (or even a 320) on either day but opted to cancel the flight altogether.

Status: We're sorry to let you know that your flight (UA 240) on June 13 has been canceled because of maintenance-related schedule disruptions.

just the usual UA maintenance issues. Hopefully not another summer from hell.

EWR-CDG cancelled last night and also a SFO-EWR rotation today cancelled on top of the LAX one. So it looks like 3 781s are out of service for maintenance ... definitely not good. UA is running soooo thin right now with the 7M9 issues that they can't sub planes anymore.

All back in service. Two unrelated issues but lack of slack in the fleet means there are fewer spares to cover maintenance-related cancellations.

Aircraft go mx. That is not unique to UA.

Thankfully, UA did not order its 781s with the RR engines, otherwise there would be some serious schedule disruptions.

That would be AA, which is in a nasty dispute with its mechanics. If you think UA is so bad, suggest you give AA a try.

I believe the 787-10 is referred to as the B78X (ICAO) or 78J (IATA), but not as the 781.

United publishes it as 781 (in Sabre at least).

Code:
 15JUN  SAT   SFO/PDT     EWR/EDT‡3

My SFO-IAD flight on June 8 was cancelled because of a maintenance issue. I believe that was also a 781

That's not correct. Aircraft have multiple designations. "781" is the standard generic designation for the 787-10. UA also refers to its 781s as the 78J, but that is specific to UA's configuration of the aircraft Just as UA's 772-200As may be referred to as "772" or 77G. Or its 772-200ERs may be referred to "772" or 77N, 77J, 77Q, 77E, or 77Y, depending on engines and seating configuration.

Totally related but unrelated. My mother in law was to be on that flight (after a 3 hour maintenance delay in ATH) she then was on ORD-SEA which had over a 6 hour delay. She was.... tired when she finally got home.

Has she considered whether she is eligible for EC261 compensation?

I hadnít seen it mentioned but DUB-EWR cancelled on Wednesday (6/12). Anyone know why? Looks like inbound arrived, and another inbound came on 6/13 and departed. Where did the 6/12 plane go?

curious whether it got reassigned to cover a fuller flight from Europe.. tried using flightaware to answer but no luck.,

You can track actual aircraft using something like flightradar24. The plane flew back to EWR from DUB on Thursday afternoon. I assume it was a maintenance issue.

They aren't going to cancel a flight and leave passengers stranded in Europe for 24 hours without good reason. They are responsible for any costs incurred by passengers for controllable delays. In addition, European law requires them to pay compensation to anyone who is delayed by more than 4 hours.

June 8, UA751 was originally a 781, but was delayed 2 hours, and swapped in a 767. One txt stated "brake maintenance" as reason for the delay.

Perils of flying a new model, and I have a habit of new aircraft chasing. My scheduled EWR-SFO 78J became a 772 a few weeks back. Nearly all flights for about a two week period had the same thing happen. DLs A220s are going MX at a pretty high rate, too. Guess it's like a new car model, sometimes you need to let someone else break them in.
