What to expect
Heading from Cusco into the forest? Start with the actual options for your date. LATAM markets the route, but check whether the selected ticket is nonstop and when it arrives. Match that arrival to the lodge transfer departure. A shorter flight helps little if you miss the pickup.
How it fits into a journey
Ask the lodge which arrivals fit. Treat the first day as a travel day and add a city night if the connection does not work well.
