Pros: "I missed my flight due to a delayed flight from denver to Washington. When I arrived I beg if there is a sooner flight to Geneva. They said no more. They book me another flight which has more connections. When I was waiting for my next flight there were actually more flight going and direct to Geneva before my flight. I even ask the gate personel if There is more seats avilable for one of those flight before my flight. They said yes but because I had a luggage it will take time to transfer my luggage and they will end up being delayed. United airlines is HORRIBLE!!! My flight were delayed and with that they should have more consideration for those costumers who were delayed. But instead of being kind and considerate. They had book me a later flight and the worse thing is the itenerary had more connections. Very Exhausting. The other costumer when we were in the line at the costumer service desk some people were given flight which are like 12 hrs away. How Horrible service. I WILL NOT FLY WITH UNITED AIRLINES AGAIN. Very POOR SERVICE."

The airline told us seats were chosen at random and they couldn't control them so we had 4 legs of our two flights stuck in no reveling seats. I was very disappointed."

Cons: "Need The Rona to be done already! No in-flight service"

Cons: "Apparently, if you pay extra for carry on luggage and you have seats in rows two and three, you can’t use the overhead compartment, which then somewhat defeats the extra legroom you paid for when your carry on has to go under the seat ahead of you. And the flight attendant was rather rude in her insistence about where my luggage “couldn’t” go."
