Frequently Asked Questions

Is flying to India turbulent?
Flying to India is generally moderately turbulent. The main turbulence sources vary by route: (1) Flights from Europe cross the Alps or Balkans, then the Zagros Mountains in Iran — moderate mountain wave turbulence possible. (2) The monsoon season (June–September) brings convective turbulence over the Indian subcontinent, particularly over central India and the Western Ghats. (3) Flights from the US or Australia may cross the Arabian Sea or Bay of Bengal, which are generally calm outside monsoon season.
When is flying to India most turbulent?
June through September (monsoon season) is the most turbulent for flights over the Indian subcontinent — convective storms are common over central India, the Western Ghats, and the Bay of Bengal. Approaching Mumbai (BOM) during monsoon can be notably turbulent. November to April is calmer, especially December to February. The Himalayas generate year-round mountain wave turbulence on routes from China or Southeast Asia.
Is Mumbai more turbulent than Delhi?
During monsoon season, Mumbai (BOM) is typically more turbulent on approach — the city sits right on the Arabian Sea coast where monsoon storms are intense. Delhi (DEL) flights from Europe overfly the Zagros and Karakoram ranges — mountain wave turbulence is a factor year-round. Bangalore (BLR) and Chennai (MAA) are in the southern Deccan plateau — generally calmer approaches but still affected by the monsoon convection.
What seat is best for flights to India?
For long-haul India flights (Air India Boeing 787 or Airbus A350, Emirates/Etihad with stop), wing seats minimize turbulence. On a Boeing 787 (used by Air India on London–Delhi), active gust alleviation significantly smooths rough air. Direct London–Delhi flights are ~9 hours; via Dubai adds a stop but breaks the flight into smoother segments. During monsoon, any seat feels the turbulence — keep your seatbelt on during all phases of flight.
Does the Arabian Sea cause turbulence on flights to India?
The Arabian Sea is generally calm for the first 3–5 months of the year. During June–September monsoon, the southwestern monsoon crosses the Arabian Sea with significant atmospheric instability — turbulence is common on flights from the Gulf or East Africa to India. The Bay of Bengal (eastern India routes) is similar — calm outside monsoon, turbulent during it. Above 35,000 ft, the Arabian Sea is usually manageable even in monsoon season.
