21 April - UA 870 from Sydney to Los Angeles ... boarding was delayed due to late-arriving crew (caught in traffic en route to airport), but flight was quickly boarded (not a full flight) and departed close to time. Economy Plus seating was decent - I had a row to myself until, about 2 hours into the flight, a flight attendant advised me that she was moving another passenger into my row. Of course that's something that they can do, but by that time I was all spread out, working on my laptop, so it was a bit disruptive to get everything sorted and moved, but what was annoying is that the flight attendant could have easily relocated the passenger to another similar row without causing so much disruption. Minor annoyance, but worth noting.
Meal service is a bit lame; United could learn a lot from American's international economy meal service, which is a LOT better.
Satellite wi-fi service was spotty and sluggish most of the flight - a bit disappointing compared to my previous experience flying United on this route.
Also, seat comfort on the 787 dreamliner is not that great. The seats are nice leather, but are thin and hard. A bit more thought could have gone into seat comfort for a long-range aircraft such as this one.
But overall, a decent - although not exceptional - flight. Arrived slightly ahead of schedule into LAX, which was a nice plus.
