Delhi To Houston Flights @ ₹51008+ Upto ₹2500 OFF

Thinking about Houston? Here's what actually matters before you book: flight time, who flies it, which airport you land at, what paperwork you need, and where the real savings are. Fares start from ₹51,008 per person on EaseMyTrip.

How Long is the Delhi to Houston Flight?

A direct Delhi–Houston flight runs about 6h 46m in the air, covering roughly 13455 km. That number shifts a bit by airline and aircraft — KLM usually runs the fastest, around 21h 20m. One thing worth knowing: the clock difference between India and Houston on your ticket isn't your actual flight time — check the duration field, not the times. With 347+ flights a day, there's not much reason to book a connection unless a specific fare or a stopover you actually want makes it worth it.

Which Airlines Fly from Delhi to Houston?

IndiGo, AIR FRANCE, Delta Airlines, KLM, Virgin Atlantic Airways and 20 more operate this route. The real difference between budget and full-service here isn't always the fare — it's what's included in it. Baggage allowance and layover length move your actual cost more than they do on a domestic booking.

Most people end up comparing all of this on EaseMyTrip instead of checking airline by airline. It's faster to see fares, baggage limits, and reviews side by side than to dig through five different sites.

Delhi and Houston Airport Information

You'll fly out of Indira Gandhi International Airport (DEL) in Delhi. Land in Houston and it's George Bush Intercontinental Houston Airport (IAH) — check your ticket for the terminal, since carriers don't all use the same one.

Do Indian Travelers Need a Visa for Houston?

Depending on your passport and travel purpose, you may need a visa, an e-visa, or qualify for visa-on-arrival for Houston. Have your documents ready before you apply, as processing times vary. Passport validity doesn't change no matter which route applies to you: keep six months left on it from your travel date, or airlines can deny you boarding at check-in. Entry rules move faster than flight schedules do, so check the official immigration site close to your travel date.

Things to Know Before Booking Delhi to Houston Flights

Book 6–8 weeks out, not the week before. That's usually the sweet spot here. November tends to run cheapest overall.
Mind the calendar on both ends. Fares climb around the Indian holiday season, and separately around Houston's own peak — local holidays, weather, events. Shift your dates by a few days and you'll usually see it in the price.
Give yourself 3 hours, not 2. International check-in eats more time — immigration, extra security screening. Online check-in usually opens 24 to 48 hours out.
Don't assume domestic baggage rules apply. International fares are more generous, but it swings a lot by airline and fare class, so actually read the fare rules.
Price round trip before you buy one-way. The gap tends to be bigger on international routes than on domestic ones.
Wed flights, plus a code. Wed departures run cheaper on this route. Stack EMTFIRST, EMTNCF, or EASEDAY at checkout on top of that.

It is located about 16 to 20 km from central Delhi and has multiple terminals, so always check your terminal on your ticket before leaving. DEL handles both domestic flights and international flights.

How to Reach Delhi Airport (IGI Airport)

The fastest way to reach Delhi airport is usually the Delhi Metro Airport Express Line, because it avoids road traffic. Other options are:

• Airport Express Metro: Connects New Delhi Railway Station to the airport in roughly 20 minutes, with other stops on the line.

How Early Should You Reach Delhi Airport?

For domestic flights, reach Delhi airport about 2 hours before departure. Allow extra time during festivals, long weekends, school holidays and foggy winter mornings. For international flights, plan to arrive 3 hours before departure.

What Are the Best Things to Do in Delhi?

The best things to do in Delhi are visiting its Mughal monuments, exploring Old Delhi’s food lanes and shopping in its markets. Top landmarks include:

• Red Fort: A UNESCO World Heritage Site and a symbol of Mughal rule.
• Jama Masjid: One of the largest mosques in India, in Old Delhi.
• Qutub Minar: A UNESCO-listed sandstone tower with detailed carvings.

For shopping, Sarojini Nagar and Janpath are popular for budget fashion, Dilli Haat for handicrafts and regional food, and Khan Market and Connaught Place for cafes and branded stores.

What Is the Best Time to Visit Delhi?

The best time to visit Delhi is October to March, when the weather is cool and suits sightseeing. This is also peak travel season, so flights and hotels fill up faster. Summers (April to June) are very hot, and the monsoon (July to September) brings some rain and slightly cooler weather.

When Are Flights to Delhi Cheapest?

Flights to Delhi are usually cheapest when booked several weeks in advance and when travelling midweek. Fares tend to rise during October to March, around Diwali, Christmas and New Year, and during long weekends. Comparing airlines, timings and baggage rules, not just the lowest fare, usually gives the best value.

Does Fog Affect Flights in Delhi?

Yes. Dense fog in Delhi, usually from December to January, can cause flight delays and schedule changes, with early morning flights most affected. Check your flight status before leaving for the airport and avoid tight connections on winter mornings.

What Happens in Delhi on Republic Day?

The Republic Day Parade takes place on 26 January on Kartavya Path, with state tableaux, military contingents and an air force fly-past. Road closures and added security can slow travel in central Delhi, and flights fill up around the date, so book early and allow extra time to reach the airport.

Which Railway Stations Serve Delhi?

Delhi’s main railway stations are New Delhi Railway Station, Hazrat Nizamuddin and Anand Vihar Terminal. If you are connecting between a train and a flight, leave a generous gap, as winter train delays are common.
