They don't collect when you get on at the airport. When you arrive at the station if you already have a ticket they let you get off first then those that need to purchase a ticket do so as you get off the bus. The driver doesn't take any money or tickets someone from inside the station comes out on the bus. It moves pretty well
I was told you pay at station when you get off. It would be nice if they sold tickets at the airport though.
I agree with the above. Also, if you get a round trip ticket you save a bit of money.
Yes, you can pay on the bus from the airport to the specific Logan Express location.
