Excellent crew, good flight. Flight was delayed about 1 1/2 hours though.

Read more about Southern / Mokulele

Excellent crew, good flight. Flight was delayed about 1 1/2 hours though.

Pros: "The ground crew and flight crew were great."
Cons: "Would have appreciated easier steps (lower risers) for boarding. Arthritic knee makes it hard for me to manage the high risers between steps. Also having armrests would have made the flight more comfortable."
Pros: "I loved the small craft and easy boarding."
Cons: "Flight is a little slower with a smaller plane, but that was expected."
Pros: "So fast and friendly crew. So much easier to fly to Morgantown, instead of driving. Plus the views from above are so great."
Cons: "Flight could not be better for a commuter connection."
Pros: "Awesome crew. Simple check-in and boarding. Beautiful, scenic views. A+!"

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.

Loading was quick and efficient. The bate and switch with discount tickets were you are forced to pay for bag.

Good flight, comfortable seats and very quick passage through Heathrow. Boarding in Washington was cramped and not well organized, but the rest was perfect.

Flight was delayed. Connecting flight left 5 people - pulled away from the gate 10 min early with no connection options until the next day !!!

Cons: "The original seats we purchased was a different plane. Only two in the row This plan was very crowded and no wiggle room to change seats"
