After a lot of research, I’m going to answer my own question.
I called HAL and asked about getting to Trieste from the VCE (Venice Marco Polo airport) and this is what I was told;
HAL only has a “complementary” bus to Trieste from the city center (what city center?)
We would be at the airport so that means it is up to us to find a way.
Bus from the airport to Trieste bus station. I chose FlixBus.
Go online to FlixBus.com and search for Venice airport to Trieste. It will then show a schedule for the day you choose. Fare runs about $19 to $25 per person depending on the time of departure.
Right now the Euro is less than the US$. You can purchase a ticket online here in the US, and receive confirmation of your reservation, you can print out or put on your phone.
To get to the bus from the airport terminal you must take one of three sheltered walkways from the terminal. The bus parks in a special bus lot across from the Tamoil service station.
It looks like about a ten minute walk (with all your luggage - carts are available in the terminal).
‘Enjoy
