The closing of Terminal 2 last year and recent addition of Terminal 3 I'm sure makes people think this city is truly as dumb as they believe ("They managed to build a whole terminal before realizing they skipped '2'?") but IT IS GREAT.
After all these years later, I still stand by my original McCarran Airport review. And one of the reasons why I still can is because of the recent addition of Terminal 3. T3 is mainly for international flights and some domestic carriers like JetBlue.
The tram to connect to this terminal makes you feel worldly, as if you were in Heathrow or JFK. Granted, when you look out of of your plane and see the Egyptian pyramids and the Eiffel Tower together through your window it's a little disillusioning knowing it's not real, but hey, we try.
