Pack light layers for Bengaluru’s pleasant October climate, including a light rain jacket for residual monsoon showers and comfortable clothing for city travel and temple visits. Ensure you apply for an India e-Visa ahead of time, check passport validity (six months minimum), and confirm any airline baggage limits for international Atlanta to Bengaluru flights. Health: carry routine medications, ensure recommended vaccines are up to date and bring hand sanitizer; COVID-19 requirements are variable, so check current airline and government advisories. At Hartsfield–Jackson Atlanta International Airport (ATL), use TSA PreCheck if eligible, arrive 3 hours before international departures, and pre-book airport parking or ride-hailing pickup.
