All flights were on time and boarding was issue free

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

Crowded flight, but upbeat and kind crew. Pilot greeted us at door, flight attendant thanked a number of “special” passengers for their business, another addressed an eight-year old boy as “young man.” United obviously trying to up their game, but though all of that is nice and notable, flying still feels like moving along a human assembly line, being herded into one small space after another (boarding areas with too few seats, planes with limited personal space, shuttles (IAD) packed too full.

It was ok until we got to DC and I wanted to use my United Club pass and the snobbish receptionist said that they don’t take one pass. It took me everything itch of patience not to tell her off

Food choice was poor and we had to buy on board snacks.

We were offer chocolate cookies , not everyone eat chocolate. Thank you

Lost luggage again. Our second trip to Mykonos, and 2nd time no luggage.

Flight was well orchestrated, made up time despite circling a bit all good on United. Travelers can just be so into themselves that common courtesy has gone out window for some, but that’s not on United.
