I will be arriving in DFW at 3pm on American Airlines in Y and transiting to Qantas J for the 10pm flight to BNE.

Will I have time to get to downtown Dallas to have a look around? I'm keen to go to the JFK museum, see Dealy Plaza and stand on the grassy knoll.

I think there is a train but not sure if it is connected to the airport.

I'm based in New Zealand.

Thanks in advance
