In order to minimize excess travel, the itinerary starts with a direct flight from Boston to Paris on Delta. It then continues with time in Chamonix, followed by Zermatt. There are a few options to avoid connecting flights on the return journey.
Option 1: travel to a city which has direct flights to Boston on Delta airlines. Major European cities include
a) London, England
b) Amsterdam, The Netherlands
c) Lisbon, Portugal
Option 2: head back to Paris from Zermatt and add an additional day in Paris
Option 3: extend time in both Chamonix and Zermatt, but plan a return journey from Zurich with a connecting flight
