Travel insurance
Check whether your bank card or home insurance already covers this trip.
If the trip needs a visa, the travel agent or visa centre usually sells the cover it asks for.
Mobile data (eSIM)
Your own plan's EU roaming may already cover this.
Renting a pocket Wi-Fi is the other common way to stay connected.
These are sites people in book with. Each opens in a new tab, on the site's own pages. Some pay us a commission if you book, at no extra cost to you; most pay nothing, and what a site pays never decides whether it is listed or where.
Month by month from Delhi
No fare history on DEL–MAA yet, so this ranking is climate and crowds only. The price column fills in as the scanner collects.

Crowds is a score out of 100 where higher is quieter. It counts public-holiday clusters in IN as well as at Chennai, which is why this table differs from the same one read from another country. A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. Crowds alone never make a month “avoid”: that is reserved for weather worth skipping.
