If I don't have to book with United again, I won't. We were flying from Charlotte to Ireland and had connecting flights to catch. They were semi-helpful getting us a new flight so we could make our connection when flights were delayed due to weather. However the seats weren't even next to each other. When traveling 8 hours transatlantic, you kind of want to be with the person you're going with.
On the return flight, it was a travel day from hell. They partner with Air lingus and we were able to check in no problem for our first flight. However, united wouldn't let us check in for our next two flights at the same time. They also didn't give us a receipt for our luggage. We had to go to customer service after landing to get our boarding passes and to make sure our luggage had made it, making us almost miss our connection. We also had to go through security 3 times even though all 3 flights were on the same trip.
In addition, every flight we were on was overbooked and people around us were frantically trying to get on the flight. They tried to make us check our carry-ons for each flight and we had to fight them saying we didn't have enough time between flights to wait for our bags. Then with what happened to that poor gentlemen getting forced off the plane... stay AWAY from United.
I gave two stars because we made it safely home. Thank you to the United pilots.
