I normally fly United to and from Chile. I will state that I am a 1K/Global Services customer so I do expect a higher level of service when I fly. But, United always comes through for me. Check-in is always good. Agents are knowledgeable, polite and helpful. On my recent flight I arrived at a C concourse gate and had to go to the E concourse. When I walked off the plane, there was a cart waiting for me and the agent explained that the walk would be quite long so they offered the cart service. United always tries to recognize their FF passengers. Business Class lounge is very good. My bags always arrive. Again, I am a FF customer of United, but they always come through for me and the agents are always helpful and polite.
