Route notes
Why this routing works
This routing is built as a compact three-week Atlantic trip with the longest flights positioned at the beginning and end: Los Angeles to London outbound, then Paris back to Los Angeles. That keeps the transatlantic sectors simple while leaving the middle of the ticket flexible for onward movement within Europe.
The itinerary uses an open-jaw structure between London and Biarritz, shown as London // Biarritz. In practice, that means the ticket covers arrival into London and resumes again from Biarritz, with the gap handled separately overland. From Biarritz, the routing continues by air to Paris before the final long-haul return.
With 11 nights listed in London, the pacing is front-loaded, leaving the remaining time for the France segment within the overall three-week duration. That sequencing can work well for travelers who want one longer stop followed by shorter final positions before returning home.
Priced from USD 1,977 to USD 3,015 in premium economy, this is a straightforward multi-stop fare for August travel in the July to September season. The route stays focused on a small number of cities, which helps keep the ticket structure clear and limits backtracking.
