Route notes
Why this routing works
This 17-week multi-stop itinerary is built around two long stays: 37 nights in Yerevan and 25 nights in Athens. The routing moves east from Los Angeles into Armenia, then threads through Jeddah and Addis Ababa before returning to Jeddah and continuing on to Greece. That sequence keeps the airborne segments grouped before a slower European finish.
The return side uses an open-jaw in Italy: arrival into Athens, overland onward to Florence, then a separate flight from Rome. That structure works well when part of the trip is planned on the ground rather than by air, and it avoids forcing a backtrack to the same airport. Florence is explicitly reached overland, so the ticket resumes from Rome rather than trying to include that surface sector as a flight.
London appears here as a 0-night layover rather than a stopover, which signals a same-day connection on the way back to Los Angeles. In practical ticketing terms, that keeps London as a transit point instead of adding another stay to the itinerary. With economy cabin travel and a September departure, this is a long-duration multi-stop route that mixes fixed flight sectors with one planned surface segment.
