This long north–south pairing now sees genuine non-stop service. IndiGo (6E) operates the direct Lucknow–Thiruvananthapuram flights, with roughly three departures on most days; the fastest of these is around 4h 15m, though some IndiGo rotations on the route run longer at about 5h 45m. Air India (AI) and Air India Express (IX) add further options, mostly via a southern hub. Because direct frequency is still modest, the daily schedule can be thin — if the non-stop times do not suit, a 1-stop via Bengaluru, Hyderabad or Delhi is always findable. Check the exact date, as the direct does not run every rotation of the day.
The great-circle distance is about 2,080 km, one of the longer domestic sectors in India. A non-stop covers it in roughly 4h 15m. A connecting itinerary — LKO to a southern hub, then onward to TRV — typically totals 5h 45m to 8h once a 1–3 hour layover is added. Via Bengaluru the BLR–TRV leg is about 1h 20m; via Hyderabad the HYD–TRV hop is roughly 1h 40m; a Delhi connection adds a long second leg of around 3h 15m. For the shortest day, prioritise the non-stop, then a southern hub. The return is covered in our routes directory.
Fares on this sector swing with Kerala's festival calendar and the school-holiday rush. Booking 4–8 weeks ahead generally lands the best value; last-minute seats on a thin direct schedule can be steep. We do not quote specific fares, as they move daily — use a fare alert and compare the non-stop against a 1-stop, which is sometimes cheaper.
| Period | Demand | Booking advice |
|---|---|---|
| Sep–Jan (Onam, festive, peak) | High | Book 6–8 weeks ahead |
| Feb–Mar, Jun–Jul | Lower | Best value; 3–4 weeks ahead works |
| Sabarimala season (Nov–Jan) | Very high | Reserve early; pilgrim demand spikes |
Set a price alert and watch both the non-stop and the 1-stop options — on a thin direct schedule, a connection via Bengaluru or Hyderabad can undercut the direct. Mid-week departures (Tuesday/Wednesday) are usually softer than weekends. Travelling with only cabin baggage and skipping seat selection trims the fare on basic classes. Book a single through-ticket rather than two separate ones so a delayed first leg is protected. Clearing cookies or comparing across sites occasionally surfaces a lower price on the same flight.
IndiGo's non-stops on this route often run late evening or overnight, which suits travellers who want to land in Trivandrum in the morning. If you prefer a connection, an early-to-mid-morning departure from Lucknow leaves the most buffer at the hub and the widest choice of onward flights to TRV. Avoid the tightest same-day connections in the monsoon, when Kerala weather can delay the final leg. For arrivals, a daytime landing makes the 6 km transfer into the city far easier than a late-night one.
Business travellers should grab the non-stop where the timing fits — it removes the layover risk on a long sector and gets you to TRV in one leg. Families may find a daytime 1-stop via Bengaluru more comfortable than an overnight direct, with a break to stretch and feed children. Students and budget flyers benefit most from booking early and being flexible on dates; cabin-only fares on a connecting itinerary are frequently the cheapest. Whatever your type, lock the through-ticket so the connection is the airline's responsibility, not yours.
Lucknow's Chaudhary Charan Singh International Airport (LKO) operates from a single integrated terminal (the newer T3 building), handling all domestic departures including IndiGo, Air India and Air India Express. Trivandrum International Airport (TRV) splits operations: Terminal 1 handles domestic flights, while Terminal 2 is for international services — so your Lucknow arrival lands at T1. TRV is a busy Gulf-travel gateway, so expect crowded periods. If you self-connect through Bengaluru or Hyderabad, note their domestic terminals and allow time to re-clear security.
Trivandrum's Terminal 1 is only about 6 km from the city centre — one of India's closest airport-to-downtown distances. App-cabs and prepaid taxis reach Thampanoor, the railway station and the secretariat area in 15–25 minutes; autos serve shorter hops. For onward trips to Kovalam beach (about 16 km) or Varkala, taxis and buses run regularly. At the Lucknow end, allow extra time in the city's traffic and aim to reach the airport about 2 hours before departure.
Cabin baggage is 7 kg on IndiGo, Air India and Air India Express in economy, plus a small personal item. Domestic checked allowance is typically 15 kg on IndiGo, with Air India often allowing more on standard fares; Air India Express and basic promotional classes may price checked bags separately, so confirm at booking. On a connecting itinerary booked as one ticket, your bags are usually checked through to TRV. For exact, fare-class-specific limits see IndiGo baggage.
Kerala's southwest monsoon (June–September) brings heavy rain to Trivandrum and can delay connecting legs, so build in buffer time and prefer the non-stop in those months. Lucknow sees dense winter fog (December–January) that can push back early-morning departures — another reason the evening non-stop is handy. Carry light, breathable clothing for humid coastal Kerala year-round, plus a compact umbrella in the wet season. During Sabarimala season (November–January), TRV and the wider region are busier than usual.
On a thin direct schedule like this, do not assume the non-stop is always cheapest — set a FlightGPT alert and compare it against a 1-stop via Bengaluru on your exact dates. If the direct's overnight timing does not suit, a daytime connection can be both cheaper and more comfortable. Book the connection as one through-ticket so the airline protects it, and reserve early for the September–January peak.

Possibly. Lucknow can see dense fog in December–January, which delays early-morning departures. An evening or overnight non-stop is less exposed; allow buffer time on early flights during fog season.
Kerala's southwest monsoon (June–September) brings heavy rain to Trivandrum and can delay connecting legs. Prefer the non-stop in those months and build in buffer time on tight connections.
IndiGo and Air India allow pets on many domestic flights subject to advance approval, health and vaccination documents, and carrier rules; Air India Express does not carry pets in the cabin. Always arrange this with the airline well before travel.
Yes. Infants under two travel on an adult's lap at a reduced fare; carry the child's date-of-birth proof. One cabin bag and often a stroller or baby essentials are permitted — check your airline's infant policy.
Prices are often similar. Airline websites sometimes have member-only deals, while OTAs let you compare carriers and routings side by side. For a thin direct schedule like this, comparing both the non-stop and a 1-stop across sources is the best way to find value.
Terminal 1 is only about 6 km from the city centre, a 15–25 minute taxi ride to Thampanoor, the railway station and most central areas.
Generally February–March and June–July, away from the September–January festive and Sabarimala peaks. Book 4–8 weeks ahead and set a fare alert for the best chance at a low price.
