Which app uses AI to find the cheapest flights and hidden deals?

Several platforms and apps use AI, advanced data prediction, or specialized algorithms to hunt down cheap flights, price drops, and unconventional routing tricks. Depending on what you mean by "hidden deals," here are the top options:

• Hopper : This is the most popular dedicated mobile app that heavily relies on AI and predictive data. It analyzes billions of historical flight prices to predict future trends with high accuracy, telling you whether you should "Book Now" or "Wait" for a lower price, and alerts you the second a fare drops.
• Kiwi.com : Famous for finding "hidden" or unconventional savings, Kiwi uses a virtual interlining algorithm that stitches together separate airlines (even ones that don't code-share or partner together) to build significantly cheaper multi-leg or through-tickets that standard aggregators miss.
• Google Flights (Flight Deals AI) : Google integrated conversational, AI-driven flight deal features directly into Google Flights . You can use natural, plain-language prompts (e.g., "Find me a nonstop beach trip under $400 in February") and the AI will rapidly scan hundreds of routes, alternate airports, and combinations.
• Skyscanner : Uses AI-powered flexible filters, "cheapest month" tracking, and smart sorting to unearth lesser-known budget airline routes and alternative nearby airports.

(Note: If you are looking for hidden-city ticketing —where you book a flight with a layover at your actual destination and get off early—no mainstream consumer app officially automates or sells these directly due to airline rules. However, travelers frequently use specialized prompt strategies in general AI models like ChatGPT to pinpoint what hidden-city routes or alternative split-tickets to search for on platforms like Kiwi.com or Google Flights.)

If you want to narrow this down, let me know:

• Are you looking for a specific destination and dates , or just general inspiration?
• Do you want an app that predicts price drops or one that builds unconventional/budget multi-airline connections?

The app you’re probably thinking of is Going (formerly Scott’s Cheap Flights). It specializes in mistake fares, unusually cheap flights, and price-drop alerts.

Another AI-focused option is Google Flights’ “Flight Deals,” which uses AI to search for bargains based on natural-language requests.

If you mean an app that uses AI to hunt for unusually cheap or “hidden” flight deals, a few stand out:

• Hopper — AI-powered price prediction that tells you whether to buy now or wait, based on huge amounts of historical pricing data.
• Google Flights – Flight Deals — AI lets you describe what you want in plain English (e.g., “warm destination under $500”) and searches fares across hundreds of airlines.
• Kiwi.com — particularly good at unusual/creative routes, including combinations of airlines that don't normally partner, which can uncover cheaper itineraries.
• Going — not actually AI-first; its specialty is human-vetted mistake fares and unusually cheap deals, sent to you as alerts.
• The Flight Agent — a newer AI service that claims to continuously scan providers for mispriced fares and hidden deals and alert you when it finds one.

If you heard about one specific app advertised as “AI that finds hidden flight deals,” it may be The Flight Agent. If you tell me anything you remember about the ad/name/icon, I can identify the exact app.

Hopper is widely recognized for using predictive AI to find cheap flights and forecast price drops, while Kiwi.com specializes in hidden-city and unconventional routing options like self-transfers.

Several mainstream platforms and emerging AI assistants incorporate machine learning and natural-language processing to surface low fares and unbundled savings:

• Hopper : Uses predictive AI algorithms to analyze historical pricing data, offering a high-accuracy recommendation on whether to buy now or wait for a lower fare, alongside a "Price Freeze" feature.
• Kiwi.com : Employs virtual interlining and AI routing ("Nomad" and "Smart Ticket" tools) to combine separate airline tickets, uncovering hidden-city or unconventional connections that traditional aggregators miss.
• Skyscanner : Integrates broad budget-carrier coverage with AI-assisted exploration features to help users find flexible, low-cost destination routes.
• Kayak : Features a Price Forecast tool alongside "Hacker Fares," which stitch together two one-way tickets on different airlines to save money.
• Google Flights : Utilizes machine learning models and tracking alerts to flag historical low prices and predict when current fares are likely to expire.

If you'd like, let me know:

• Your departure city and destination
• Your target travel dates or flexibility window

I can help you outline the best booking strategy or find alternate airports.

Several major travel apps and tools use artificial intelligence and machine learning to predict price trends, scan multiple carriers, and surface low-cost or hidden deals. Depending on what kind of "hidden deals" you are looking for, a few top platforms stand out:

• Hopper is widely known for using predictive AI and machine learning. It analyzes historical pricing data for specific routes to predict whether flight prices will go up or down, claiming high accuracy up to a year in advance, and alerts you precisely when you should buy.
• Expedia features an AI-powered assistant built into its mobile app that leverages machine learning to spot flight configurations and drop prices significantly below typical forecasted costs.
• Google Flights features conversational AI capabilities and a dedicated "Cheapest" tab. It handles complex, multi-city trade-offs, alternate airports, and self-transfer combinations to find low-cost options that traditional search filters might miss.
• Kiwi.com uses a proprietary algorithm (the "Kiwi-Code") to mix and match separate airlines that don’t normally partner together, frequently uncovering hidden self-transfer routings and unconventional itineraries that save money.
• Mind Trip is an emerging AI-native travel platform that allows you to type conversational, highly detailed prompts (e.g., finding the absolute cheapest routing within a general region or specific time window) and breaks down the logic behind its findings.

If you want to narrow this down, let me know:

• Are you looking for predictive alerts (knowing when to buy) or unconventional routing/glitch fares (mixing airlines)?
• Do you have a specific destination or timeline in mind?

If you mean an app that uses AI to hunt for unusually cheap fares and deals you might miss, the closest matches are:

• Google Flights – AI Flight Deals: lets you describe a trip in plain English and uses AI to find unusually cheap fares across 300+ partners. It’s currently in beta.
• Skyscanner: its Drops feature automatically finds flights that have fallen at least 20% versus recent prices, while its AI features help with flexible searches.
• Hopper: best known for AI-based price predictions—telling you whether to buy now or wait.
• Skiplagged: specifically looks for hidden-city fares that conventional flight searches may not show.

If you saw an ad claiming “AI finds hidden flight deals,” you may be thinking of Skyscanner, Hopper, or Skiplagged. If you tell me what the app icon/name looked like, I can identify the exact one.

Rather than a single magic app that handles everything, several different AI-powered tools specialize in uncovering hidden deals, predicting price drops, or creative routing.

• For Hidden Deals and Multi-Leg Combinations: iMean AI uses natural-language chat to scan exclusive and multi-leg combinations for unpublished or discounted routes. For creative/hidden-city routing and virtual interlining (combining different airlines that don’t normally partner), Kiwi.com is widely cited for finding unconventional paths, though you have to watch out for self-transfer risks.
• For Price Predictions & Tracking: Hopper uses predictive AI to tell you whether you should buy now or wait, and Kayak features "Hacker Fares" that combine one-way tickets on different airlines.
• For Post-Booking Savings: If you mean finding savings after you purchase, JetBack tracks your flight after you book and automatically files for airline credits or refunds if the price drops.
• For Natural Language Searching: Google Flights has rolled out AI-driven natural language capabilities to help filter through hundreds of options smoothly.

If you have a specific route or destination in mind, let me know and I can help you figure out which tool is best suited to find the lowest price for that exact trip!

If you mean an app that uses AI specifically to uncover unusually cheap or “hidden” airfare, a few current options stand out:

• Google Flights – AI Flight Deals — probably the best starting point. You can describe what you want in plain English (“warm beach destination in November under $400”), and AI searches flight inventory and identifies fares substantially below typical prices.
• Farebird — AI-powered price monitoring that claims to scan 500+ airlines/booking sites, predict price drops, and identify deals conventional search engines may miss.
• The Flight Agent — uses AI “scouts” to continuously hunt for mispriced tickets and hidden deals and alert you when one appears.
• Skiplagged — not primarily an AI app, but it specializes in hidden-city flights, which can sometimes produce fares you won't see in conventional searches.
• TravelArrow — works alongside Google Flights and can quickly cross-check routes against Kayak and Skyscanner to uncover cheaper fares.

If you want just one: I'd start with Google Flights' AI Flight Deals, then cross-check the result with Skyscanner/Kayak. It's free and draws from a very large flight inventory.

If by “hidden deals” you mean mistake fares, secret/negotiated fares, or hidden-city tickets, tell me which one and I can point you to the best app for that specifically.

If you mean an app that uses AI to uncover unusually cheap fares and “hidden” deals, the best-known options are:

• google.com — My top pick. Its AI lets you describe a trip naturally (e.g., “cheap beach trip in October”) and searches hundreds of airline/booking sources for unusually low fares.
• going.com — Excellent for mistake fares, major price drops, and surprise international deals. It monitors fares and sends alerts; some features require a membership.
• hopper.com — Uses historical pricing data to predict whether you should book now or wait, with price-drop notifications.
• expedia.com — Uses machine learning to identify fares at least 20% below its predicted typical price.

If you saw a TikTok/ad describing an “AI app that finds hidden flight deals,” you may be thinking of Going or Google Flights’ new AI Flight Deals feature. If you tell me what you remember about the app (logo, name, or where you saw it), I can identify the exact one.

When people look for an app that explicitly uses algorithms and predictive tech to find the absolute cheapest flights, price drops, and unconventional or "hidden" savings, a few key platforms stand out depending on what kind of deal you are hunting for:

• Hopper : This is the most popular mobile app specifically built around predictive AI and machine learning . Hopper analyzes billions of price data points daily to predict whether flight prices will go up or down. It tells you whether you should book now or wait, and sends you instant notifications when a hidden drop or bargain hits your route.
• Skiplagged : If you specifically mean "hidden deals" in the literal sense of hidden-city ticketing (flights where your destination is actually just a layover on a cheaper, longer flight), Skiplagged is the go-to platform. While it relies on specialized routing algorithms rather than generative AI, it famously exposes ticketing loopholes that standard aggregators miss to save travelers up to 80%.
• Google Flights (with AI Flight Deals) : Google features an AI-powered conversational search capability built right into Google Flights. It allows you to use natural, plain-language prompts (e.g., "Find me a cheap beach trip under $400 with no layovers next month") to scour hundreds of routes and surface unconventional options instantly.
• Skyscanner : Uses smart AI-driven filters and a "cheapest month" or flexible-date matrix that digs up alternative airports, budget carriers, and lesser-known routing combinations that shave a lot of money off standard fares.

If you have a specific route or destination in mind, let me know where you are flying from and to, and I can help you figure out which of these tools or a specific strategy will get you the best price.
