Mumbai to Delhi is the country’s single busiest domestic air route — the financial capital talking to the political capital, all day long. With over 60 non-stop flights daily, operated by five carriers, a flight departs roughly every 15 minutes during peak business hours. That frequency gives you extraordinary flexibility. But it also means fares can swing dramatically depending on the day, time, and how far in advance you book.
This guide is specifically about finding the cheapest fares on this route — not just comparing airlines, but understanding the booking patterns that consistently deliver lower prices. Whether you travel this route once a year or once a month, the strategies here will save you real money.

Route Overview: Mumbai (BOM) to Delhi (DEL)
The BOM–DEL corridor connects Chhatrapati Shivaji Maharaj International Airport in Mumbai with Indira Gandhi International Airport in Delhi. The aerial distance is approximately 1,150 kilometres, and a direct flight covers it in 2 hours 10 minutes to 2 hours 25 minutes. It is India’s most trafficked domestic route, handling over 10 million passengers annually according to DGCA annual traffic data (DGCA, 2025).
Both airports have multiple terminals relevant to this route:
- Mumbai T1: IndiGo, SpiceJet, Akasa Air, Air India Express domestic flights
- Mumbai T2: Air India domestic flights — more spacious, premium lounges
- Delhi T1: IndiGo and SpiceJet domestic flights
- Delhi T3: Air India domestic and international flights
Always verify your terminal at the time of booking — arriving at the wrong terminal at either airport costs you 30–45 minutes and real stress.
Which Airlines Fly Mumbai to Delhi in 2026?
Five carriers compete on this route, with a combined 60+ daily non-stop departures. According to DGCA monthly traffic data (DGCA, 2025), IndiGo holds approximately 55–60% market share on BOM–DEL, making it the dominant operator. But market share doesn’t mean cheapest fare — here’s the full picture:

| IndiGo | 20–25 | Economy, Stretch | ₹3,000 – ₹8,500 |

What Is the Cheapest Month to Fly Mumbai to Delhi?
Unlike leisure routes, BOM–DEL is a business-dominant corridor. Fares follow working-week and corporate-calendar patterns more than seasonal holiday patterns. That said, two genuinely cheap windows exist each year — and they’re worth planning around if your travel dates are flexible.
The Two Cheapest Windows of the Year
Late January through mid-February sees fares drop to ₹2,800–₹3,800 on weekday departures. The post-Republic Day lull, combined with low leisure travel, creates a genuine buyer’s market. June through mid-July is the second window — monsoon dampens leisure travel, and many corporates reduce business trips during the slow quarter.
Month-by-Month Fare Guide
| Month | Demand Type | Typical One-Way Fare (Economy) | Booking Tip |
|---|---|---|---|
| January | Moderate (post-holiday) | ₹3,500 – ₹6,500 | Budget session travel starts late Jan |
| February | Low (cheapest window) | ₹2,800 – ₹4,500 | Best month for budget travel |
| March | Moderate (Q4 year-end) | ₹3,500 – ₹6,500 | Corporate quarter-end boosts demand |
| April | Moderate | ₹3,200 – ₹6,000 | IPL season adds leisure demand |
| May | Moderate–High (school holidays) | ₹3,500 – ₹7,000 | Book early; family travel drives demand |
| June | Low (second cheapest window) | ₹2,800 – ₹4,000 | Great value; monsoon reduces demand |
| July | Low–Moderate | ₹3,000 – ₹4,500 | Parliament Monsoon Session adds demand |
| August | Moderate | ₹3,200 – ₹5,500 | Independence Day weekend spikes briefly |
| September | Moderate–High (Q2 end) | ₹3,500 – ₹6,500 | Corporate quarter-end activity |
| October | High (Diwali) | ₹5,000 – ₹11,000 | Book 45–60 days ahead |
| November | Moderate–High | ₹4,000 – ₹8,000 | Post-Diwali easing by mid-November |
| December | High (year-end) | ₹4,500 – ₹10,000 | Christmas week needs 60-day advance booking |
The Cheapest Booking Formula
Book 15–30 days ahead, choose a Tuesday or Wednesday, and pick an early morning (before 7 AM) or mid-day (11 AM–3 PM) departure. On HappyFares, this combination consistently surfaces fares in the ₹2,800–₹3,800 range during off-peak months.
Mumbai to Delhi: Flight or Rajdhani Express?
The Rajdhani Express (12951/12952) is the flagship train on this route, covering the 1,384 km journey in 15–17 hours with meals included. It’s a genuine alternative for budget-conscious travellers or those who enjoy the overnight train experience. Here’s an honest comparison:
| Factor | Flight | Rajdhani Express |
|---|---|---|
| Journey Time | ~2 hrs 15 min | 15–17 hours |
| Total Door-to-Door | 4–5 hours | 16–18 hours |
| Cost (Economy / 3AC) | ₹2,800 – ₹8,000 | ₹2,500 – ₹3,500 |
| Meals | Buy on board (LCC) / included (Air India) | Included in Rajdhani fare |
| Luggage | 7–15 kg (fare-dependent) | No practical limit |
| Overnight option? | No | Yes — arrive rested in the morning |
| Best For | Time-sensitive travel, day trips, business | Budget travel, heavy luggage, overnight comfort |
The train’s core advantage is cost when flight fares are high — and the ability to carry unlimited luggage. But when fares on HappyFares dip below ₹3,500, the 12–13 hour time saving is hard to justify skipping. For a day trip or quick business visit, flying is the only sensible option.
[UNIQUE INSIGHT] One often-overlooked strategy: the Rajdhani departs Mumbai at around 4:55 PM and reaches Delhi by 9–10 AM the next day. For travellers who don’t want to pay a Mumbai hotel night, this can be a smart “save the hotel night” move. But it only makes financial sense when flight fares are above ₹5,000.
Packing Tips for the Mumbai to Delhi Route
Delhi and Mumbai have very different climates, and packing wrong is a surprisingly common mistake on this route.
October to February (Delhi Winter)
Mumbai stays warm (22°C–32°C) year-round. But Delhi winters are genuinely cold — temperatures can drop to 4°C–8°C in January. If you’re flying from Mumbai to Delhi between November and February, carry at least one warm layer in your cabin bag. Checked baggage fees on budget carriers run ₹500–₹1,200, so packing smart within 7 kg saves money.
March to September (Summer and Monsoon)
Both cities are hot and humid in this period. Light cotton clothing works for both. For the monsoon months (June–August), a compact travel umbrella or light raincoat is worth adding — Delhi gets heavy rain and Mumbai’s monsoon is famously intense. A small dry bag for electronics is a good precaution.
Cabin Baggage Tips for LCC Flights
- 7 kg cabin baggage limit applies on IndiGo, SpiceJet, and Akasa Air economy fares
- One personal item (laptop bag, small backpack) is typically allowed in addition
- Weigh your bag before leaving home — airport baggage fee counters charge a premium for even slight overages
- If you need more, add checked baggage at the time of booking — it’s significantly cheaper than paying at the airport
