The cancellation rate based on flightaware doesn't reveal much about the 787's reliability at UA
, it merely highlights some (to be expected) lacking flexibility with their small fleet of six. A larger fleet with more opportunity for substitutions could have reduced the cancellation rate to zero, even if the flights had been substituted by other types. And on the flipside, in June there were at least 8 instances where 787s went tech and had to be swapped for another with subsequent delays - without being cancelled. That said, Bloomberg's report paints a blurry picture, at best.
It would have been more interesting had they dug a little deeper to report on the number of delays incurred by technical issues. Better yet, had they managed to press UA
for some solid dispatch reliability figures - rather than a generic PR
response which is even less revealing than their flightaware stats. But the way things are currently going, I don't see UA
being too eager to release such.

For example, from June 1 - June 30, ANA operated 1844 787 flights, and experienced a total of 13 flights with delays or cancellations, meaning that 99.3% of ANA's 787 flights operated normally.
They experienced a total of 13 flights with cancellations or delays in excess of 2 hours
. That doesn't mean the other 99.3% operated normally.
On the 4th of July, for example, their PDF shows one cancellation for KMJ-HND
. Yet HND
had a maintenance delay of 1.5 hours and HND
-TOY was substituted by a different type with subsequent delay - neither of which made the list. I'm not familiar with other days, just happened to be looking into their fleet utilization at the time.

Once a carrier has the plane in service for a year or so and has a decent size fleet, operating experience and parts and people in the right places - the dispatch rate will get better.
No doubt, yet the 787's dispatch reliability rate at United
is well below par for the introduction of a new type.
Today's UA70 LAX
was cancelled as well after a 3 hour servicing delay. Aircraft is still stuck at LAX
