I would like to know how to reach the international airport for a 730 am flight from Zurich Airport if I am staying in Lucerne. Are trains running at night?
Did you check the timetable (www.myswissalps.com/ti metable)? That allows you to find such answers. As for this specific question: if your flight leaves at 07h30, I assume you have to be present at the airport well in advance. The earliest train from Lucerne departs at 04h55 and arrives at Zurich Airport at 06h13, which is too late I think. You'd better spend the night in a hotel close to Zurich Airport, to ensure an easy and early arrival at the airport: www.myswissalps.com/zu richairporthotels.
