Where do you buy the transbrigde bus tickets at LVA?

inside the building on the lower level, right by the baggage claim carousels.

Melissa Rios....you can buy bus tickets at the information desk located on the lower level across from the entrance. There are 2 spots outside along the curb for customers who are buying tickets as well

Is there a bus that leaves the airport to go to Flemington New Jersey?

I agree with these two answers.
