Top tips for finding a cheap flight out of George Bush Intercontinental Houston Airport (IAH)

Book within the Goldilocks Window

People often think that as departure dates get closer, flight prices should decrease. It would make sense. Airlines need to fill seats, so they would put them up for sale at the last minute. But we’ve found that’s not true, partly because business travelers often book last-minute flights and can afford higher prices. In fact, we’ve found prices tend to rise as flights get close and are almost guaranteed to rise at the 21-day, 14-day, and 7-day points.

That’s why we recommend booking in the Goldilocks Window, a period not too close to your desired departure date but also not too far away. That’s 1-3 months before a domestic flight and 2-8 months before an international flight. If you’re planning to travel during a busy period, like the 4th of July weekend, winter holidays, or other generally busy times (summer is busy everywhere), start looking even a few months farther ahead.

Use the Greek Islands Trick

Hoping to fly from Houston to Santorini this summer, but flights are outrageously expensive? Try the Greek Islands trick. This is where you look at flights near your final destination, like London, Istanbul, or Rome, in this case, then find a cheap flight for the last leg. Often, individual flights within Europe are much cheaper than international flights to popular cities or islands.

The Greek Islands Trick works for plenty of destinations, not only the Greek Islands. If you’re hoping to go somewhere very popular, or with a small airport, or that is for some other reason very expensive on your travel dates, look for the closest place you can find that’s affordable. From there, you might even be able to take a ferry or train. It requires more planning, but the savings often make it worth it.

Search additional airports

Travelers in Houston have several options nearby, and you’re probably already used to looking at flights out of William P. Hobby Airport, Galveston, or the Gulf Coast Regional Airport. If you have time to make the drive or take a short extra flight, why not try Dallas or Austin, too?

Or, try looking even farther away, like LA, Atlanta, or Chicago. It might seem strange to look for flights out of a city so far away from Houston that it requires an extra flight to get there, but it can be worth it. We’ve found deals like $63 from Atlanta to Chile roundtrip. Or $202 from Los Angeles to Japan. For those kinds of deals, even if you add a $200 flight from Houston to Atlanta, you’re still likely saving hundreds of dollars.

Fly on days when it's cheaper

Like much of the world, summer is the busiest time to fly out of Houston. Not only are kids out of school, but sweltering temperatures and hurricane season mean Houstonians want to get out of the city for a bit. Spring and fall are known as the best seasons to visit Houston, so flights can be expensive then, too.

Try to travel during the winter if you can, when flights are cheapest. Or travel during shoulder season, the time between peak and low travel times. This is when we’ve typically found great deals. Plus, you get the advantage of seeing the world with fewer crowds.

If you plan to travel during summer or other peak times, try to fly on Tuesday, Wednesday, and Saturday. These are the cheapest days to fly, while Friday and Sunday are usually the most expensive.

Sign up for fare alerts

One of the easiest ways to save time and money is to set a flight alert on Google Flights or by joining Going. This way, you get price drops sent directly to your email, and you don’t have to worry about checking them daily. Then, when a flight drops into a range you’re comfortable with, you can purchase. We recommend setting these up at least a few months ahead of when you plan to travel.

Houston is a major hub for United Airlines and Spirit Airlines. Both offer dozens of domestic and international flights. Plus, there are 27 other airlines departing from Houston, and the airport has nonstop flights to 180 destinations. With so many options, you can get to most places with one connection or less.

How early should I arrive to George Bush Intercontinental Airport (IAH) before my flight?

IAH recommends that passengers arrive at least two hours before a domestic flight and three hours before an international flight. But this is one of the largest and busiest airports in the United States, so actual times depend on a few factors.

Where is your gate? IAH is a big airport, and getting across it can take upwards of 20 minutes. Look at what gate you’re flying from and estimate how long it will take you to walk or take the SkyTrain from the check-in area. If you’re driving, factor in an extra 10 minutes or so for walking from your parking spot.

Try to check in online. Most airlines cutoff check-in 30-60 minutes before the flight departs. If you check in online, you can do it hours ahead and not have to worry. If you can’t, make sure you get to the airport before that window.

Are you checking luggage? Airlines also implement baggage check cutoffs, typically 45-60 minutes before the flight is scheduled to take off. If you plan to check a bag, make sure to arrive before this time.

How busy is the airport? The average security line wait time at IAH is about 20 minutes. But if you’re traveling during peak times and on weekends, it can be much, much longer.

We recommend arriving at IAH 1.5-2 hours before your flight or 2.5 hours before on a busy travel day.

How far is George Bush Intercontinental Airport (IAH) from downtown Houston?

George Bush Intercontinental Airport (IAH) is about 20 miles from downtown Houston, depending on where in the city you’re departing from.

What are the different transportation options for going from the city center to George Bush Intercontinental Airport (IAH)?

There are several options for traveling from Houston to IAH.
