Flight Deals from Houston to Calcutta from $863

Houston to Kolkata is about 8,815 miles. There is no scheduled nonstop service on this route, so the journey requires a connection.

Methodology

Flight times and distances come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.

There are no direct flights from Houston to Kolkata. The shortest connecting routing is on Qatar Airways via Doha, taking 21 hours and 25 minutes in total (14 hours 55 minutes on the first leg, a 1 hour 40 minute layover, and 4 hours 50 minutes on the second leg). Emirates also connects through Dubai on a longer 26 hour 5 minute itinerary.

Methodology

Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours.

The fastest way from Kolkata Airport to the city center is a prepaid or app-based taxi, which takes roughly 18–20 minutes for the 15–17 km trip and runs 24/7; Uber and Ola are readily available, with typical fares around ₹970. Air-conditioned Volvo and Marcopolo buses operated by WBSTC serve Esplanade, Howrah, Tollygunge, and other hubs at very reasonable charges, though journey times stretch to 1–1.5 hours. The Kolkata Suburban Railway connects via Biman Bandar station, but it sees poor patronage due to irregular intervals and limited destinations. Car rental with a driver is available and recommended for foreign visitors. Taxis are the most-used option for direct airport transfers, while buses remain the budget choice for locals.

There are no nonstop red-eye flights from Houston to Kolkata, but an overnight connecting itinerary operates with Qatar Airways: the long leg from Houston (IAH) to Doha departs at 18:15 and arrives at 17:10 the following day, then connects at Doha with a 1h40m layover before continuing to Kolkata.

Methodology

Red-eye flights are identified from scheduled local departure and arrival times and block times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes. A flight counts as a red-eye when it departs in the afternoon or evening (3 p.m. or later local time) or in the early hours before 4 a.m., and is in the air at some point between midnight and 4 a.m. local time at both its departure airport and its arrival airport. An evening flight that lands before midnight at its destination is never counted, nor is a morning departure or a daytime long-haul that reaches the next calendar date only because of time zones. Each red-eye is labelled with its timing (for example, overnight and landing the next morning, or late-night and landing after midnight). For connecting itineraries the same rule is applied to the longer leg, from one representative day's flight search.

There is no nonstop service from Houston to Kolkata; the usual routings connect through Doha on Qatar Airways (about 21h 25m total) or through Dubai on Emirates (about 26h 5m). Qatar Airways is a oneworld member, while Emirates is not part of any alliance.

Kolkata has one commercial airport, Netaji Subhas Chandra Bose International Airport, about 17 km northeast of the city centre. It serves all flights to and from the city.

METRO Bus 40 and the express Bus 500 serve downtown Houston from Hobby Airport, with the express costing $4.50 and running every 30 minutes. Taxis are available at Curb Zone 2 with a flat fare of $29 to downtown, while ride-hailing apps like Uber and Lyft pick up at Curb Zone 5 and typically cost slightly less than a taxi. Driving yourself is straightforward with two self-parking garages near the terminal, and off-airport parking shuttles depart from Curb Zones 3 and 4. Ride-share is the most popular choice for its balance of speed and cost, while the express bus is the cheapest option.

Kolkata airport has retiring rooms and dormitory beds inside the terminal for short stays, available 24 hours to passengers with a confirmed onward flight, with twin-sharing retiring rooms around ₹1,000 per bed, family or double-bedded rooms around ₹1,500, and dormitory beds around ₹700. Nearby hotels include the Holiday Inn Express Kolkata Airport, located 0.4 miles from the terminal with no airport shuttle, and the Novotel Kolkata Hotel & Residences, about a 20-minute drive away with a shuttle available on call. The airport itself has no dedicated sleeping areas or quiet rest zones, and seating has armrests that make stretching out difficult, so the retiring rooms are the best option for uninterrupted sleep.

There is no nonstop service from Houston to Kolkata, so all flights connect. Qatar Airways offers a one-stop route through Doha using an Airbus A350-1000 on the long leg and an Airbus A350-900 on the short leg, while Emirates connects through Dubai with a Boeing 777-200LR on the long leg and a Boeing 777-300ER on the short leg.

Methodology

Aircraft types come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.

There is no nonstop service from Houston to Kolkata; the route is flown via one-stop connections. Qatar Airways (a oneworld member) connects through Doha, and Emirates — which belongs to no alliance — connects through Dubai. Other alliances may reach Kolkata via connections, but these two carriers are the ones currently operating the route.

When departing from Houston's William P. Hobby Airport, the best lounge options are the Gameway Lounge, a gaming-focused space near Gate 1, and the USO Lounge, which serves military members and their families. Hobby does not have any traditional airline lounges, so these two spaces are the primary choices for travelers looking to relax before a flight.

Same‑day changes and standby depend on the airline and fare class; flexible economy, premium economy, and business tickets typically allow them, while the lowest fares do not.
