Booking Cheap Direct Flights

Regarding travel in the United States, I always look for cheap direct flights first. The time and energy saved by flying non-stop are worth the sometimes added cost.

Plus, you're less likely to miss a connecting flight due to the weather, system failures, or overbooking if you don't need one. If you're traveling with only a carry-on, you're also not at risk of lost luggage.

When you've got a connecting flight, there's less room for error, and given the soaring demand for air travel these days, it's best to minimize the odds of something going wrong.

Direct Flights offers the easiest way to search for more than 70,000 direct flights worldwide. And amazingly, they don't require you to set up an account or log into the website.

Austin to JFK

I'm currently researching direct flights from Austin-Bergstrom International Airport (AUS) in Texas to John F Kennedy International (JFK), a major airport in New York City.

Entering those two airport codes provides me with a wealth of data on the next screen (shown below).

I can quickly see that JetBlue (my preferred airline), American Airlines, and Delta all offer daily non-stop flights from Austin to JFK and that the flight time is typically 3 hours and 40 minutes.

Scrolling down on the search results page shows specific flight times for all the airlines and more information about the airline alliances, plane models, and arrival terminals.

When I click the blue box labeled “show return schedule,” it reveals the return flight times for me to depart JFK (New York City) for Austin, TX.

Clicking on any of the individual yellow boxes for a flight brings up an info box with additional details.

If I click the green box to “check prices for AUS – JFK,” a calendar pops open, and I can select my travel dates, whether researching one-way flights or round-trip flights, number of passengers, and the seat (economy or business class).

After putting in my preferences, I click the green button to “check prices” and am redirected to, where I can see the cheapest flights and proceed to book the best option.

Why use Direct Flights?

The Direct Flights website is helpful in the early phase of flight research when you may only want to find out if there are direct flights between your departure city and destination.

It can be helpful whether you're looking for one-way tickets or round-trip, and you don't even need to know the date(s).

Plus, it's free, easy to use, and doesn't require you to create an account, which privacy advocates will appreciate.
