Route Overview: Guwahati (GAU) to Delhi (DEL)
The GAU–DEL sector covers approximately 1,700 kilometres and is classified as a Tier-1 domestic route by DGCA. According to DGCA traffic statistics for 2025, Guwahati Airport (Lokpriya Gopinath Bordoloi International Airport) handled over 7 million passengers annually, with Delhi as its single busiest destination. The route sees particularly high demand during Assam’s Bihu festivals and the autumn festive season.
A non-stop flight takes 2 hours 45 minutes to 3 hours. Connecting flights via Kolkata (CCU) or Hyderabad (HYD) exist but add at least 3–4 hours to travel time and rarely offer meaningful savings. Direct is almost always the right call here.
Which Airlines Fly Guwahati to Delhi in 2026?
The GAU–DEL route has strong competition, which keeps fares reasonably healthy year-round. Here is the current operator landscape:
| Airline | Daily Non-Stop Flights (Approx.) | Typical One-Way Fare | Notes |
|---|---|---|---|
| IndiGo | 4–6 | ₹3,200 – ₹9,000 | Highest frequency, early morning slots popular |
| Air India | 2–3 | ₹3,800 – ₹10,500 | Full-service, good for families with luggage |
| SpiceJet | 1–2 | ₹3,000 – ₹8,500 | Competitive pricing on this sector |
| Akasa Air | 1 | ₹3,100 – ₹8,000 | Newer entrant, growing North East presence |

When Are Guwahati to Delhi Fares Cheapest?
The GAU–DEL route follows demand patterns driven by Assam’s cultural calendar, academic cycles, and seasonal tourism. Understanding these patterns is the clearest path to cheaper tickets.
| Month | Demand Driver | Fare Range (One-Way) | Booking Tip |
|---|---|---|---|
| January | Post-holiday lull | ₹3,200 – ₹5,500 | Republic Day week spikes briefly |
| February | Low demand | ₹3,000 – ₹4,800 | One of the cheapest months |
| March | Holi travel, exams | ₹3,500 – ₹6,000 | Holi week sees brief spike |
| April | Rongali Bihu | ₹5,500 – ₹12,000 | Book 6–8 weeks ahead or expect high fares |
| May | School holidays | ₹5,000 – ₹10,000 | Families travelling to Delhi relatives |
| June | Monsoon, college start | ₹3,800 – ₹6,500 | Students returning to Delhi colleges |
| July–August | Monsoon off-peak | ₹3,000 – ₹5,000 | Best value months |
| September | Pre-festival shoulder | ₹3,500 – ₹6,000 | Book early for Durga Puja |
| October | Durga Puja + Kongali Bihu | ₹6,000 – ₹14,000 | Book 8+ weeks ahead — fares spike hard |
| November | Post-festival drop | ₹3,500 – ₹6,500 | Good value after October crowds |
| December | Christmas, year-end | ₹4,500 – ₹9,000 | Bhogali Bihu preparation travel in late Dec |
Key insight: The GAU–DEL route has two sharp peaks — April (Rongali Bihu) and October (Durga Puja / Kongali Bihu). These are North East India’s most important cultural festivals. Airlines fill up quickly and fares double or triple. If your travel dates overlap with these windows, booking 6–8 weeks in advance is not just advised — it’s necessary.
[CITATION CAPSULE: According to DGCA’s 2025 domestic traffic data, Guwahati (GAU) is the busiest airport in North East India, handling over 7 million passengers annually. The Delhi route accounts for the single largest share of Guwahati’s seat capacity, reflecting the strong people-movement between Assam and the national capital. (DGCA, 2025)]
Advance Booking Tips for This Route
The Guwahati–Delhi sector rewards early bookers more than many other domestic routes. Here’s why: the North East’s student population creates a predictable booking pattern, with seats on popular early-morning and late-evening flights selling out 4–6 weeks ahead during academic cycle peaks (June and November).
Best Practices for Getting the Lowest Fare
- Book on weekdays: Tuesday and Wednesday departures on the GAU–DEL sector are consistently 10–20% cheaper than Friday and Sunday flights.
- Early morning flights: The 5:30–7:00 AM departures from Guwahati typically offer the lowest base fares because they’re less popular with business travellers who prefer later slots.
- Set a fare alert: Use HappyFares to monitor price movements on your travel dates. Fares on this route can drop ₹800–₹1,500 in a single week if an airline adds inventory.
- Round-trip vs. one-way: On this route, round-trip bookings sometimes unlock a 5–8% discount over two separate one-way tickets. Always check both options.
- Avoid booking within 7 days: Last-minute fares on GAU–DEL spike sharply, especially because it’s not a route where unsold seats get dumped cheaply — demand absorbs them at premium prices.
Pro Tip: The Bihu Booking Rule
Rongali Bihu falls in mid-April and Kongali Bihu falls in late October every year. These are the two hardest dates to book on the GAU–DEL sector. Mark your calendar 8 weeks before these festivals — that’s when airlines typically release seat inventory for peak festival departures. Set a reminder and check HappyFares the moment dates open up.
