4 Ways To Use AI To Find the Cheapest Airline Tickets

Though it's premature to break out the holiday decorations, that doesn't mean you shouldn't start planning your end-of-year vacations now to get a jump on the best priced airline tickets.

Rising airfare prices make finding deals increasingly difficult. ChatGPT can't book flights for you, but it can guide your search, ask the right questions, and reveal money-saving strategies.

Here are four practical ways to use ChatGPT to find cheaper airline tickets.

Unfortunately, to save a little money, you sometimes have to spend a little. To use the Kayak plugin on ChatGPT Plus, first ensure you have a $20 per month subscription. You then navigate to the Plugin Store in GPT-4, search for "Kayak," and install it. Once enabled, ask ChatGPT to find flights, hotels, or rental cars, providing specific details like dates, budget, or destination for real-time recommendations.

The Kayak plugin will handle your request to find the cheapest airline tickets. You can post specific questions, such as, "What are the cheapest round-trip flights from Los Angeles, CA to Dallas, TX from November 21 to November 28?"

The Kayak plugin will post results with links so you can book the flights immediately.

The Expedia plugin for ChatGPT Plus works in a similar way to the Kayak plugin. Users can post their requests to the chatbot and receive results with links that will allow them to book their flights on Expedia.

To use the Expedia plugin on ChatGPT Plus, you also enable it via the Plugin Store under the GPT-4 model. Once enabled, ask for travel, such as "Find me hotels in London from May 1-5". Feel free to add specific details to your query, such as "I prefer a long layover," to get more personalized results, and the plugin searches real-time data for flights, hotels, and activities, providing direct links to book on Expedia.

Trip.com offers a plugin for ChatGPT Plus that can help you find cheap flights. Simply type in your query and wait for the results. Click on the corresponding link for the flight you want, and you'll be able to book it right away.

To use the Trip.com plugin on ChatGPT Plus, once again enable GPT-4, open the Plugin Store, install "Trip.com," and activate it in a new chat.

If you don't have ChatGPT Plus, you can still use ChatGPT to find the cheapest airline tickets. However, you'll have to do more of the legwork than you would when using the Kayak plugin.

First, enter details about your travel dates and destination. For instance, you could use the same example from above, "Find the cheapest airline tickets for a round-trip from Los Angeles, CA to Dallas, TX from November 21 to November 28."

Note that there are no links like you'll find when you use the integrated travel plugins in ChatGPT Plus. Instead, it gives you an idea of what airlines are offering the cheapest fares for your chosen itinerary. You'll then have to look up the airfares and book the tickets yourself.

ChatGPT also stated that the prices are subject to change and additional fees may apply. It suggested visiting the respective airline's website or using a trusted travel booking platform to secure tickets at the best price. It also recommended comparing options and factoring in baggage allowances and flight times to allow you to make an informed decision based on your preferences and budget.
