Need help with airport to use to visit Bedollo from USA

My husband and I will be visiting family in Bedollo next May. We are trying to figure out which airport to fly into. Then, what type of transportation should we use from airport to Bedollo? After we visit there, we are planning to go up to Vienna, so I would love advice on transportation options from Bedollo to Vienna. I’m not terribly concerned about the budget, but would enjoy trains over flights, when possible. Thank you in advice!
