The United flights were OK. Recently the Direct flight to Charleston, WV was changed to arriving after 10 PM. Previously it was earlier in the day. Options for ground transportation after 10 PM in Charleston are not as viable as day time options. So, I took a flight from Houston to Washington Dulles and a connecting flight to Charleston. There is not much time between flights at Dulles. IAD is a busy place. I barely made my flight.
I will say though the flight from Dulles to Charleston on United Express was quick and ahead of schedule. I prefer a direct flight but ,this was OK.
My luggage arrived safe and on time.
Using the United APP does save time especially with the boarding pass.
