Route notes
Why this routing works
This six-week itinerary uses a straightforward westbound-to-eastbound transatlantic sequence from Los Angeles to London, then continues overland-style within Europe by ticketing onward air segments to Stuttgart and Rome before returning to the United States via Chicago. Ending with a domestic stop before the final return to Los Angeles keeps the route linear and avoids unnecessary backtracking.
As a multi-stop ticket, this routing is structured around a single continuous sequence rather than separate round-trips. That can simplify pricing across three European stops plus a U.S. domestic stop, while keeping the trip contained within a clear six-week frame. The May departure timing places the itinerary in the apr-jun season window, which is useful for travelers trying to lock in fixed dates across multiple cities.
In economy class, the main planning value here is the balance between stop count and routing simplicity: four stopovers between departure and final return, with only one transatlantic outbound and one transatlantic inbound crossing. Chicago works as the final U.S. stop before returning to Los Angeles, which can make the homebound portion easier to sequence than routing straight back from Europe.
