Today was my first (and probably last time, at least for a while) time flying through Lugano's tiny…read moreairport. I imagine that more of the service is geared towards private flying (particularly based on the number of private jets I saw vs. the 4 daily scheduled flights, all to Zurich), but as such, it makes transiting through here a cinch. We were heading out on the first flight (a 7:30 AM departure), but even arriving ~70 minutes prior to departure was frankly too early. There's a small parking lot to the right where we dropped off our rental car (followed by subsequently dropping off the keys in a keybox), and inside the terminal, pre-security, is a ticket area on the right, which is easy to mistake for the check-in area (which is further in to the left). Since only SWISS flies here, you have 2 lines - one for business, one for economy. It took us less than 5 minutes to get checked in all the way back to the U.S., as well as having our bags checked all the way as well. Security screening is quick and easy - just make sure to take out liquids and laptops/tablets - and then there is a small seating area that has a small duty-free shop and a cafe. There's (literally) nothing else post-security (I'm not even sure that bathrooms are available airside), hence the advice for not showing up that early. When you board, you simply walk out onto the tarmac and up on the plane. If you're lucky to have a southbound takeoff, you will circle around and back north, affording you beautiful views of the area around Lugano, as well as views of the Swiss Alps further west, if the weather cooperates.
I imagine that Lugano often gets overlooked because it isn't all that far away from a much larger airport (Milan's Malpensa airport) - but I intentionally picked it because I figured that it would be much less of a hassle to start our trip back to the U.S., even if it meant an extra stop via Zurich (which I like as an airport anyways) - and it worked out just as I thought. The only risk is that, given the dearth of flights, you could be in a little trouble making onwards connections if there are any scheduling issues. That said, our experience worked like a charm. If you are either visiting Lugano or the surrounding area - or are traveling elsewhere and can fly direct to your destination via Zurich - I would definitely recommend looking into LUG as a convenient, low-stress point to begin or end your journey.
