United Airlines was good overall. Advanced plane and on time service.

Anonymous, Sept 2026

My flight was cancelled, I was rebooked on another flight to Paris, almost missed my flight as I had a short connection. They had to call a car to take me to board the plane in Paris. My luggage was sent to London, received it 3 days later. I missed taking few of my meds.
