Hello, my family of four plans to travel to Switzerland in June or July 2020 from the US. I am in the early planning stages of this trip, and I am already looking up flights. I typically start with Kayak. The best rates are with Vayama. Has anyone used Vayama to book European Flights from the US? I am looking at flying into and out of Zurich, but other recommended airports are fine too. We will stay in the Berner Oaberland four nights and Lucerne 4 or 5 nights (two bases).
I have traveled to Europe several times, but I would still appreciate any other flight purchasing recommendations would greatly be appreciated.
Thanks
