The best travel data APIs in 2026: a category map

Most shortlists for "travel data API" go wrong before the first vendor call, because the phrase covers four products that do not substitute for each other. A price scraper cannot issue a ticket. A booking platform is a poor way to fill a chart. An airport database will never tell you what a seat costs today.

So this page is a map, not a ranking. Four categories, the question each one answers, the question it will not answer, and named options I checked live on 2026-09-02 with the URL next to the number. Where a page publishes no price, that is what I say.

Disclosure up front: I sell in category one. I run FlightPowers, which is a price intelligence API for flights and hotels. I do not sell in the other three, and the booking-side section below says plainly that we cannot do what those vendors do.

The four categories

1. Price intelligence, also called shopping

Answers: what a fare or a room costs right now, across dates and routes, and whether the number is high or low against its own history.

Will not answer: whether that price is still there in ten minutes, whether the seat is held for you, or what the passenger name record says. Nothing in this category creates an order.

I am not going to rank vendors here, because that is what the two dedicated pages are for. For flights in depth, read the best flight data APIs in 2026. For hotels in depth, read the best hotel data APIs in 2026. Both open by disclosing that I sell one of the entries, quote every competitor from their own live page, and name where a competitor beats me.

The two named options, so this section is not empty:

• FlightPowers, mine. From the live listings on 2026-08-26: flights from $10 a month for 2,500 requests ($4.00 per 1,000) up to $50 for 50,000; hotels from $10 for 2,000 up to $50 for 25,000. Vendor speaking.
• Makcorps, for the cross-OTA version of the hotel question. From makcorps.com, read 2026-09-02: "200+ OTAs tracked", a demo of "30 Free API calls", and plans at "$350 Per Month" for 10k requests and "$500 Per Month" for 50k.

You are in the wrong category if your sentence contains the word "book", "issue", "confirm" or "refund". Go to category two.

2. Booking and ticketing

Answers: can I create an order, hold inventory, take the payment and issue the ticket or the reservation inside my own product.

Will not answer: anything cheap at scale about prices you never intend to sell. These platforms are priced around the transaction, so a research or monitoring workload is the wrong shape for them.

We do not do this. Not on flights, not on hotels. No FlightPowers endpoint books anything, and if the transaction happens inside your product, no amount of price data substitutes for the vendors below.

Duffel. From duffel.com/pricing, read 2026-09-02: "$3.00 per order" charged monthly on every confirmed order, with a "1500:1 search to book ratio" allowance and "$0.005 per excess search" beyond it. Their Stays product is described as a profit share on every completed stay, with the rate set by contacting their sales team, so there is no public per-unit number for stays on that page. For a seller that converts, the search allowance means search is close to free. For a workload with no orders the allowance is zero and every search is $0.005. Full comparison at /compare/duffel.

Booking.com Demand API. From developers.booking.com/demand, read 2026-09-02: the page asks "Are you a Managed Affiliate Partner? If so, this is for you!" and lists stays, car rentals and attractions, with flights and airport taxis described as coming soon. The overview page describes onboarding as obtaining an authentication token. No price appears on either page I read, and I did not find published sign-up terms on them, which is a claim about those two pages and not about the partner programme.

Amadeus, observed state on 2026-09-02. The Self-Service category and pricing URLs both 301-redirect to developers.amadeus.com/, the sandbox host test.api.amadeus.com did not resolve in DNS, and the developer homepage returned a JavaScript shell with no readable product text to the fetcher I used. That is what I checked and what it returned. It is not a claim that Amadeus has no hotel or flight product; Enterprise access generally runs through an account manager and accreditation. If you are migrating off Self-Service, the mapping is at /compare/amadeus.

You are in the wrong category if you never take money for the trip. A fare alert, a rate-parity dashboard and a chatbot that suggests trips are all category one, and paying per order for them makes no sense.

3. Reference and static data

Answers: what is this airport code, which airline is this, what routes exist, what is the published schedule, what aircraft is it, where is the plane now.

Will not answer: what any of it costs. Reference data is about the world, not the market. This is the category people land in by accident when they search for "flight API" and end up with a schedule feed when they wanted a fare.

aviationstack. From aviationstack.com/product, read 2026-09-02: real-time flights with delays described as "as little as 30-60 seconds", historical flights covering the last 3 months, flight schedules, future flights, airline routes and autocomplete. Coverage stated as "10,000+ Airports", "19,000+ Airplanes", "300+ Airplane Types", "13,000+ Airlines", "9,000+ Cities", "250+ Countries" and "500+ Aviation Taxes". Plans on that page: Free at $0 for 100 requests a month, Basic $49.99 for 10,000, Professional $149.99 for 50,000, Business $499.99 for 250,000, Enterprise custom.

FlightAware AeroAPI. From flightaware.com/commercial/aeroapi, read 2026-09-02: a Personal tier of up to $5 free per month at 10 result sets per minute, Standard at "$100/month" minimum plus per-query fees at 5 result sets per second, and Premium at "$1,000/month" minimum plus per-query fees at 100 result sets per second. Billing is usage-based per result set, which their page defines as 15 records. Standard adds historical data, flight alerting, airport information and routes.

Note what neither of them sells: a price. Schedules and positions are a different product from fares, and mixing them up is the most common shortlist error I see.

You are in the wrong category if your feature has a currency symbol in the mockup.

4. General-purpose scraping platforms

Answers: can I read travel sites as one of many sources, on shared infrastructure and one bill, without running proxies myself.

Will not answer: anything travel-specific that the underlying site does not already show. These platforms are horizontal, so travel is one engine among dozens and the travel-shaped conveniences are yours to build.

SerpApi. A Google scraping platform where flights and hotels are two engines among several dozen on one credit pool. Their pricing page, read 2026-09-02, states "Only successful searches are counted toward your monthly searches. Cached, errored, and failed searches are not", and their Production tier and above carries what they describe as up to $2 million in coverage for scraping and parsing search engine data. The per-engine detail and the quoted head to head is at /compare/serpapi, and the vendor-by-vendor pricing sits in the two category-one guides rather than here.

Bright Data. From brightdata.com/products/web-scraper/booking, read 2026-09-02: a free tier of "5K records per month", pay as you go at "$1.5/1K record", a Scale plan at "$499/month" including 384,000 records with more at "$1.3/1K", and custom enterprise pricing. Output as "JSON, NDJSON, JSON lines, CSV, and .gz files (compressed)" delivered to Amazon S3, Google Cloud Storage, Google PubSub, Microsoft Azure Storage, Snowflake or SFTP. The unit here is a record, not a request, which is the thing to hold on to when you compare it against anything in category one.

You are in the wrong category if you need one travel answer inside a user request and you are about to build a job runner, a proxy pool and a parser to get it.

The decision, in one line

Read your requirement out loud. The verb picks the category.

• "Show a price." "Compare rates." "Alert when it drops." Category one.
• "Sell a seat." "Hold a room." "Issue a ticket." "Refund an order." Category two.
• "Look up the airport." "List the routes." "Track the aircraft." Category three.
• "Collect pages from many sites into a warehouse." Category four.

If two verbs appear in the same sentence, you have two vendors, and pretending otherwise is how a six-week integration turns into six months. The most common real pairing is category one for the shopping experience and category two for the transaction, because the vendor who sells you the booking rail is rarely the cheapest way to answer "is this a good price".
