Terminal 3 at McCarran airport opened in June 2012 and welcome International flights and couple national flights
I really like that easy accès and friendly airport.
free wifi
I used the Terminal when flying to Europe with British Airways or Condor.
Departure are located on the top floor of the airport
easy drop off area, never too busy
Arrival are located in bottom floor
The Immigration is never too busy and honestly it took me 30mns from de-boarding, pass immigration, pick up my luggage and pass Customs last 3 time I flew to Europe
I used to work for an international airlines in LAX. just a little tip for you
NO need to rush 3h prior your flight to catch your flight unless you like to wait in line for checkin and hunt for some duty free items.
Agents who will board you are the same that are checking you in... boarding usually start 30mns prior to flight take off.
be at the airport 1h prior your flight is good enough
to make sure your bag doesn't exceed the weight allowance, you can always check on the scales of empty counter that way you can repack if needed
TSA screening is fast at McCarran T3
inside terminal 3, free wifi you just have to sign in to get it
they have a small duty free for international passengers.
Couple fast food vendors
Bon Voyage!
