Difference between "Line" and queue"

Hi,
AmE versus BrE. http://dictionary.cambridge.org/define.asp?key=64873&dict=CALDshould explain.

So from what I understood..

Are you in the queue for tickets? = British// Are you in the line for tickets = American?

Here are my American versions:
Are you in the queue for tickets? = British// Are you in the line for tickets = American?
Is this the line for tickets? (or "to purchase tickets")
There was a long queue of traffic stretching down the road. = British // There was a long line of traffic stretching down the road = Ame

In the UK, the word mad has all the other definitions (mentally ill, silly, hurrying and enthusiastic)
