Sit on the Right side of the plane for the best views on flights from Delhi to Trivandrum. Right-side seats capture the more dramatic geography: the Yamuna and Delhi's urban landscape on departure, then the Western Ghats mountain range during the cruise phase as you fly south, and finally the coastal approach to Trivandrum. Left seats offer the backwaters on arrival but miss the midpoint mountain scenery.

During takeoff from Indira Gandhi International (DEL), sit on the Right side for the best views. DEL typically departs runway 28L/R heading southwest. Right-side seats offer views of the Yamuna River floodplain and the urban sprawl of South Delhi, while left seats face the industrial areas north of the airport. The right side captures more geographic variety as you climb. Notable sights include: Yamuna River (visible as a meandering ribbon below), Delhi's southern urban districts, Aravalli Hills appearing as low ridges on the distant horizon to the southwest.

When landing at Thiruvananthapuram International (TRV), sit on the Left side for the best views. TRV uses runway 09/27; typical approach is from the north on runway 09 (heading east). Left-side seats during descent offer views of the backwaters and coastal landscape. As you descend toward the airport on the southern coast, the left side captures the Vembanad Lake and Arabian Sea approach, while right seats face inland terrain. Notable sights include: Vembanad Lake (large brackish lagoon system), Arabian Sea coastline, Thiruvananthapuram city and port area.

The flight from Indira Gandhi International (DEL) to Thiruvananthapuram International (TRV) takes Approximately 2 hours 45 minutes to 3 hours 15 minutes.

The Western Ghats mountain range becomes visible roughly 90 minutes into flight as you cross central India. These mountains form a north-south ridge along India's western coast, appearing as a series of blue-gray ridges and valleys. The Deccan Plateau extends to the right (east) of the Ghats. Major cities like Bangalore and Hyderabad lie inland to the east but are typically too distant to identify clearly. As you approach the southern coast, the terrain becomes greener with visible coconut plantations and the landscape flattens toward Kerala's backwater system.
