Hello. The charges of traveling from Chennai to Mumbai depend upon the mode of transport you are taking.

Broadly, there are three ways you can travel - roadways, railways, and air travel.

Personally, I would suggest that you book Chennai to Mumbai flights since that is what I prefer usually. A lot of people feel hesitant to travel by air if they have other options since there is a misconception that flights are expensive.

However, if you book flights from a budget airline, the charges can be quite lower. Even lower than rail tickets sometimes! But that depends on several factors...such as the time of the day your flight will be departing, the present season, deals and discounts offered by the airline or the OTA, and so much more.

For instance:

Airline tickets for the Chennai to Mumbai route can charge up to Rs 3300- 350O for an early morning flight. This price has been gotten after I ran a search for April 2021 and may change depending on several factors.

Plus, there are many discounts and deals that you can benefit from which can considerably reduce your air ticket prices. Some ways you can cut down on the prices are -

Book tickets for weekdays - You will find that prices for weekend flights are often more expensive than on weekday flights. That is because there are more people willing to travel on weekends, especially on long weekends than on weekdays. This results in a surge in the prices. You can avoid this surge by travelling on weekdays.

Check all the discounts you are eligible for - Senior citizen discount, students discount, credit card discount, seasonal offers...do not forget to check all the discounts you are eligible for to get a reduction on the prices.

Book directly through the airline - It is preferable to book directly through the airline instead of through an OTA as that means you do not have to pay the extra charges and additional fees of OTAs.

Hope my answer proves helpful to you! Have a safe journey.
