Route notes
Why this routing works
This itinerary is built as a clean eastbound loop from Monterrey, using three international stops before returning to the origin. The longest stay comes first in Lyon at 6 nights, followed by 4 nights in Istanbul and 4 nights in Singapore, which keeps the pacing front-loaded before the final long-haul trip home.
Ticketing is straightforward because every sector is flown with no surface gaps or open-jaw segments to manage. That makes the route easy to read as a single continuous sequence: Mexico to France, onward to Turkey, then to Singapore, and back to Monterrey.
At 2 weeks total in economy, the plan balances a multi-region routing with relatively even stop lengths after the first stay. Departing in December, it compresses Europe and Asia into one continuous trip rather than splitting the routing across separate tickets or return paths.
