Good flight. However, when booked flight with United, assumed the layover included by United in San Francisco of 1 hr and 40 minutes was sufficient . Not so and would recommend at least 2 hours or more. Needed to go through US immigration (very long lineups), then pick up bags, take all the way to another terminal, running because we did not have sufficient time. We made the flight because they held the door for us but luggage didn’t follow.

Unfortunately weather delayed our flight waiting for our plane to arrive and due to a little snow time was needed to deice the plane so departure was very delayed and I missed the connecting flight

Reliable, nice crew, I fly often on that flight and I like it all.

I like flying first class, and United has a nice one

It was good but only meal served is very less. Meantime good to add rice and chicken in one of meal

The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect

I had two piece luggage allowance and yet I had to pay for one of them.

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

Lufthansa was great from Lisbon to Frankfurt. The United Airlines flight from Frankfurt to Denver was very cramped. In that tight space, when the seat in front was fully declined I could barely move. I'm a fairly small person, I can't imagine what a larger person would feel like.

IAD with the archaic people movers is just a place to be avoided.
