Five airlines operate direct flights on the MAA-BOM sector in 2026. IndiGo leads the route with 6–10 daily departures, giving travellers a wide range of timing options throughout the day. The combined schedule means there’s typically a departure every 1–2 hours during peak hours (DGCA schedule data, 2025). Competition between carriers keeps fares from spiking too far outside peak season.
| Airline | Daily Direct Flights (Approx.) | Cabin Classes | Typical One-Way Fare |
|---|---|---|---|
| IndiGo | 6–10 | Economy, Stretch | ₹2,800 – ₹8,500 |
| Air India | 2–3 | Economy, Premium Economy, Business | ₹3,500 – ₹16,000 |
| SpiceJet | 2–3 | Economy | ₹2,800 – ₹8,000 |
| Akasa Air | 2–3 | Economy | ₹2,800 – ₹7,500 |
| Air India Express | 1–2 | Economy | ₹2,900 – ₹7,500 |
Compare all five on HappyFares. On many dates, there’s a ₹500–₹1,500 spread between the cheapest and most expensive airline at comparable times — a comparison that takes under a minute but can meaningfully reduce your ticket cost.
When Are Chennai to Mumbai Fares Cheapest?
Like most metro-to-metro business routes, the MAA-BOM corridor follows a demand pattern driven by corporate travel and seasonal leisure spikes. The cheapest months are February, March, and September, when fares regularly fall to ₹2,800–₹5,000 one-way (HappyFares fare tracking data, 2025). The Diwali-Dussehra period and summer school holidays are the most expensive windows.
| Month | Demand Level | Typical One-Way Economy Fare |
|---|---|---|
| January | Moderate | ₹3,200 – ₹5,500 |
| February – March | Low | ₹2,800 – ₹5,000 |
| April | Rising | ₹3,500 – ₹6,500 |
| May – June | High (Summer Holidays) | ₹5,000 – ₹10,000 |
| July – August | Moderate (Monsoon) | ₹3,200 – ₹6,000 |
| September | Low | ₹2,800 – ₹5,000 |
| October – November | High (Festive Season) | ₹5,000 – ₹10,500 |
| December | Moderate-High | ₹4,000 – ₹8,500 |
Flight vs Train: Is It Worth Flying Chennai to Mumbai?
This is a question many Chennai-Mumbai travellers genuinely weigh up, and the answer depends on your priorities. The flight takes 2 hours; the fastest train (Chennai-Mumbai Superfast Express) takes approximately 26–27 hours. That time difference alone makes flying the default choice for most travellers. But cost is where the comparison gets interesting.
| Factor | Flight (Economy) | Train (2AC Sleeper) |
|---|---|---|
| Travel Time | 2 hours 15 minutes | 26–27 hours |
| Typical Off-Peak Cost | ₹2,800 – ₹5,500 | ₹2,200 – ₹3,200 (2AC) |
| Typical Peak Cost | ₹5,000 – ₹10,000 | ₹2,400 – ₹3,500 (2AC) |
| Baggage Included | 15 kg on most budget fares | Generous (70 kg+) |
| City Centre Convenience | Airport-to-airport (outside city) | Central station |
| Cancellation Flexibility | Moderate (airline policy) | Good (IRCTC rules) |
For business travellers and anyone with time constraints, flying clearly wins. The cost difference between a budget flight and a 2AC train ticket has narrowed significantly in recent years, especially when you book 3–4 weeks ahead. For those with heavy luggage, no time pressure, and a preference for a scenic overnight journey, the train remains a viable alternative.
[UNIQUE INSIGHT]: One often-overlooked cost in the flight-vs-train comparison is airport transfer. Both Chennai Airport (MAA) and Mumbai Airport (BOM) are 25–35 km from city centres. Factor in ₹500–₹800 each way for airport taxis when doing a true cost comparison — this can add ₹2,000–₹3,200 round-trip to the total flight cost.Tips to Save Money on Chennai to Mumbai Flights
Getting a cheap fare on this route consistently comes down to four habits. We’ve tracked fares on this corridor over several months and these patterns hold up reliably.
Book 3–5 Weeks Ahead
Booking 21–35 days before departure typically secures fares 25–35% lower than booking in the final week (Ministry of Civil Aviation fare analysis, 2025). The corridor has enough daily capacity that fares don’t spike as early as on thin routes, but last-minute availability is priced as a premium. The sweet spot is 3–5 weeks out.
Prefer Mid-Week Departures
Monday and Friday see the highest demand on this business corridor — outbound travellers heading to Mumbai on Mondays and returning on Fridays. Tuesday, Wednesday, and Thursday flights are meaningfully cheaper, often by ₹600–₹1,500. If you’re visiting Mumbai for leisure, shifting departure to Wednesday can effectively pay for a night’s dinner.
Try Early Morning or Late Night Departures
The 6 AM and 6:30 AM departures from Chennai are consistently the cheapest time slots of the day. Night flights departing after 9 PM are also cheaper than peak daytime slots. Both options save ₹500–₹1,200 versus a 10 AM departure. On a 2-hour flight, the discomfort of an early alarm is minimal.
Check Total Fare Before Booking
Base fare headlines can be deceptive. Baggage charges, convenience fees, and fuel surcharges vary by airline and fare class. Always compare the all-in price on HappyFares, which shows the complete fare including taxes with no add-on charges at checkout.
[PERSONAL EXPERIENCE]: The lowest fares on the MAA-BOM route appear reliably on Tuesday and Wednesday mornings — not just in terms of departure day, but also as the day of the week when prices are most likely to reset lower. Checking fares mid-week rather than on weekends often surfaces lower options that sell out quickly.Airport Information: Chennai and Mumbai
Chennai International Airport (MAA)
Chennai International Airport handles all commercial domestic flights from a single integrated domestic terminal (Terminal 1). The airport is located in Meenambakkam, about 20 kilometres from Chennai city centre (T. Nagar/Anna Nagar). Cabs via app platforms and prepaid taxis are available outside arrivals. Allow 90 minutes before departure for domestic check-in.
Mumbai Airport (BOM) — Know Your Terminal
Chhatrapati Shivaji Maharaj International Airport has two domestic terminal buildings. Terminal 1 (T1) handles most low-cost carrier domestic flights, including IndiGo and SpiceJet. Terminal 2 (T2) handles Air India domestic flights and all international services. The terminals are separate buildings — arriving at the wrong one means a 15–20 minute taxi ride between them. Always check your terminal when booking on HappyFares.
