Cheap flights from Chennai to Bangkok

June is the lowest-priced month on this route, and it sets the low point for the year rather than a single lucky fare. From there, prices tend to rise around December and January and during school holidays, while the rest of the year moves more gently, so a flexible traveller has room to choose. Weekday departures are often cheaper than weekend ones, and the month you pick matters more than the day of the week. For December, January and the main holiday periods, book well ahead; for quieter months, you can wait a little longer, but always compare a few dates before you commit.

Some itineraries connect through an intermediate airport, while others fly nonstop, and that difference shows up in total travel time and in what the fare covers. Indigo, Thai AirAsia, Thai Lion Air, Air India, Srilankan Airlines, Thai Airways Intl, Scoot, US-Bangla Airlines, Air India Charters and Singapore Airlines all appear on this route, but not every carrier flies nonstop. On this route you will see both no-frills fares and fuller fares; the airline name alone does not tell you which is which, so read the inclusions before you pay. One fare may include checked baggage and seat selection, while another charges for them, and connection times vary by itinerary.

Arriving late in the day changes how you leave the airport, since trains and buses thin out and you may need a taxi or a hotel near the terminal. Suvarnabhumi International is the larger airport east of central Bangkok, and Don Mueang International sits to the north, with rail and road links from both. They are separate airports with different connections into town, so confirm which one your booking uses before you travel. If you land at one and need to reach the other, allow for a cross-city transfer.

Country facts: Wikidata

• Check passport validity and visa rules for Thailand before booking, since entry requirements depend on nationality.
• Confirm the Bangkok airport on your booking, because Suvarnabhumi and Don Mueang are separate airports.
• Compare baggage allowances on no-frills and fuller fares before you pay, especially if you plan to carry more than a cabin bag.
• If your itinerary connects on separate tickets, allow enough time and check whether bags are checked through.
• Cross-check your dates against the calendar, because June is the cheapest month and holiday periods can cost more.
• Watch for late arrivals and the extra cost of getting into town after public transport thins out.
