A very clean terminal. The biggest issue you have the TSA lines are way too long. It should not take almost an hour to get trough security. If you are a person who is running behind good luck making your flight. The employees are too busy taking to each other instead of getting the people to their planes on time.
You have some great bars and restaurants at terminal 3. The plus about terminal 3, is you don't have to take the monorail to the terminal. Flying out of terminal 3 would be last choice. No questions that terminal 3 is way understaffed.
