While takeoff favors the right, the landing approach and the majority of the flight path over the Arabian Sea and Kerala backwaters strongly favor left-side seats. The Western Ghats and the dramatic transition from open ocean to the intricate lagoon system are the most visually distinctive features of this route.
Flown RML to TRV? Did we get it right?
Flight Path
Colombo to Trivandrum is 233 miles (375 km), a flight of about 1 hour 10 minutes.
The flight crosses the Arabian Sea at roughly 10,000–25,000 feet. The midpoint occurs over open water approximately 40 nautical miles southwest of the Kerala coast. No major landmarks are visible at midpoint—only the sea surface, occasional fishing vessels as tiny dots, and the distant Western Ghats on the eastern horizon. As the aircraft approaches the Indian coast, the backwater system becomes increasingly visible: Vembanad Lake, Ashtamudi Lake, and the complex lagoon network that characterizes the Kerala coast. The descent path brings views of coconut plantations, small towns, and the gradual rise of terrain toward the Western Ghats interior.
