Chennai (MAA) is geographically the closest hub to Colombo, with the MAA–CMB non-stop taking only ≈ 1h 20m — making the full journey from Patna via Chennai one of the most efficient. Air India, IndiGo, and SriLankan Airlines all operate MAA–CMB. The PAT–MAA leg (≈ 2h 10m, served by IndiGo daily) allows a comfortable same-day connection. Delhi is an alternative for travellers who prefer more scheduling options — DEL–CMB non-stops on Air India take ≈ 3h 30m, and PAT–DEL runs ≈ 1h 20m. Mumbai (BOM) is a middle-ground option with BOM–CMB taking ≈ 2h 45m.
As of June 2026, combined PAT–CMB economy return tickets (booked 6–8 weeks in advance) range from ₹18,000 to ₹32,000. The Chennai hub often yields the cheapest total, especially when IndiGo runs promotions on the MAA–CMB sector. SriLankan Airlines sometimes offers attractive prices on the DEL–CMB or BOM–CMB legs and includes a generous 30 kg checked baggage allowance in economy. Air India is the go-to for single-PNR check-through convenience via Delhi. Avoid booking travel during Poya (full-moon) public holidays, the Sinhala-Tamil New Year (mid-April), and Vesak (May) when Colombo hotels fill fast.
Jay Prakash Narayan Airport (PAT) processes only domestic flights; there is no international departure hall. Passengers connecting internationally must pass through the hub airport's immigration/customs. For the Delhi hub, allow ≥ 3 hours between domestic arrival and international departure at T3; for Chennai, 2.5 hours is sufficient at the consolidated terminal. App-cabs from Patna city to the airport take ≈ 15–25 minutes depending on traffic near Gandhi Setu. Departure terminals at PAT are compact — arrival 1h 30m before domestic departure is sufficient.
Colombo's Bandaranaike International Airport (CMB) is located in Katunayake, ≈ 35 km north of Colombo Fort. The airport has a single passenger terminal with two piers. Taxis to central Colombo cost ≈ LKR 2,500–3,500 (≈ ₹750–1,050) via the expressway (≈ 35–45 minutes). The airport express train (≈ LKR 200 / ₹60) runs to Colombo Fort station and is the budget option, taking around 1 hour. Reputable apps like PickMe and Uber operate in Colombo for local transport. SIM cards with data are available at the arrivals hall kiosks (Dialog, Mobitel) for ≈ LKR 500–1,000.
Indian citizens must obtain a Sri Lanka Electronic Travel Authorisation (ETA) before arrival. In recent years, India was intermittently included in fee-waiver programmes — verify at /visas whether the free ETA scheme is currently active or a fee (≈ USD 20–35) applies. The ETA grants a 30-day single-entry stay and is applied for online via eta.gov.lk. Processing is usually instant (automated approval). Biometric data is not required; simply fill the form with your passport and travel details. A confirmed return ticket and accommodation details are advisable at immigration. Confirm current rules before booking.
Colombo is Sri Lanka's commercial capital — the Pettah market district, Galle Face Green waterfront, and Colombo National Museum make for a full day's urban exploration. Day trips extend easily to Galle (2h south by expressway bus, ≈ LKR 150–200) and the Pinnawala Elephant Orphanage (≈ 1.5h north-east). For Bihar travellers with Buddhist-circuit interests, Colombo–Kandy–Anuradhapura forms a natural 3–4 day loop connecting Theravada sites. Kandy (3h north-east by train or bus) hosts the sacred Dalada Maligawa (Temple of the Tooth). Sri Lanka's roads are scenic but slow — budget twice the map distance in time.
No — Patna has no international service. The best routing is PAT to Chennai (≈ 2h 10m via IndiGo), then Chennai to Colombo (≈ 1h 20m) — total flying time ≈ 3h 30m, plus a 2–2.5h layover.
Combined return economy fares in June 2026 typically run ₹18,000–₹32,000 booked 6–8 weeks ahead. SriLankan Airlines via Delhi sometimes offers lower all-in fares, including a 30 kg baggage allowance.
Yes — an ETA (Electronic Travel Authorisation) is required. It is applied for online via eta.gov.lk and normally approved instantly. India has periodically been included in a free-ETA scheme; otherwise the fee is ≈ USD 20–35. Check /visas for current status.
Chennai (MAA) is the most efficient hub — the MAA–CMB sector takes only ≈ 1h 20m, and IndiGo flies PAT–MAA daily. The total flying time via Chennai is the shortest of any Indian hub.
No — both cities share UTC+5:30. Sri Lanka and India are on identical time zones, so there is zero jet-lag on this route.
May–June and September–October (Sri Lankan shoulder months) offer the best fares, typically ₹18,000–₹24,000 return. April (Sinhala-Tamil New Year) and December–January (peak tourist season) are the most expensive months.

There is currently no non-stop service between Patna and Colombo — itineraries connect via a hub, with a typical journey of ≈ 4–5.5h (1-stop via DEL, BOM, or MAA).

Expect Patna–Colombo fares to vary by cabin, baggage and how the fare is bundled. A bare low-cost fare can end up dearer than a full-service carrier ticket once you add a bag and a seat. FlightGPT shows the all-in price for each option, so you're comparing like for like rather than misleading lead-in fares.
