United recently changed terminal at the Las Vegas airport and they are now located a the brand new Terminal 3. It's mot a big change as far as the gates are concerned as they are still operating from "Concourse D", a large remote gate complex. Before if you arrived at the concourse the only option is to take an automated tram to Terminal 1. Well now you have to be careful as there is two tram lines. One for Terminal 1 and one for Terminal 3. If you fly on United you have to go to Terminal 3 otherwise you won't be able to get your checked luggage back!
Terminal 3 has a more modern layout than Terminal 1 and is easier to navigate so it's a nicer experience arriving here on United. United's service for me here this time was a flight between Washington Dulled and Las Vegas. The flight was nice and on-time. Delivery of luggage was quick. All in all, nothing exceptional but still a experience that match or surpasses my expectation which as low for american carriers.
