The global travel technology market was valued at USD 8.6 billion in 2022 and is expected to reach USD 13.3 billion by 2027, growing at a CAGR of 9.1% (source: MarketsandMarkets). Over 60% of online travel bookings are facilitated through APIs, making them essential for real-time data access, reservations, and pricing.
One of the most widely adopted systems, Amadeus API Integration, has empowered countless travel platforms with access to flights, hotels, and car rentals. However, as the travel industry evolves, developers and businesses are beginning to ask: What comes after Amadeus?
This article explores the future of travel APIs, assessing new technologies, emerging platforms, and technical considerations that may shape the next generation of travel systems.
Evolution of Travel APIs
Travel APIs started as XML-based connectors between Global Distribution Systems (GDS) and booking platforms. The Amadeus API Integration simplified access to real-time availability, pricing, and booking services.
Key shifts in travel API evolution include:
- RESTful API architecture replacing SOAP-based systems
- Mobile-first development increasing real-time demand
- Open-source SDKs and dev kits improving implementation speed
- Microservices allowing modular travel platforms
Despite Amadeus’ leadership, new players and technological advances are pushing the boundaries.
Limitations of Traditional APIs like Amadeus
While Amadeus offers comprehensive coverage, it is not without limitations:
- Complex onboarding for smaller agencies and developers
- Limited flexibility in customizing search and pricing models
- High dependency on legacy GDS infrastructure
- Lack of granular data for personalization
These limitations have sparked interest in alternative or complementary solutions that provide more modern, scalable, and flexible options.
Trends Shaping the Next-Generation Travel APIs
1. AI and Machine Learning Integration
AI-driven APIs are enabling predictive pricing, smart itinerary planning, and contextual trip suggestions.
- Google Travel APIs use AI to forecast flight delays.
- Hopper applies machine learning to suggest the best times to book.
2. Blockchain for Travel Contracts and Identity
Blockchain APIs are introducing decentralized booking systems:
- Winding Tree allows airlines and hotels to offer inventory directly.
- Travala uses blockchain for bookings and payments with transparency.
3. NDC (New Distribution Capability)
IATA’s NDC protocol is transforming air content distribution:
- Enables rich media offers and branded fares
- Offers direct airline connectivity without GDS dependency
- Amadeus is NDC-compliant, but newer platforms are building NDC-first APIs
4. Voice and Conversational Interfaces
APIs are evolving for voice and chatbot-based bookings:
- Skyscanner and Expedia offer Alexa and Google Assistant integrations
- APIs support natural language inputs and contextual booking experiences
5. Sustainability-Focused APIs
Eco-conscious APIs offer CO2 emission data and green travel alternatives:
- Google Travel Sustainability API provides carbon impact metrics
- Encourages users to select greener travel options
Key Players Emerging After Amadeus
The future of travel APIs will likely be multi-platform. Here are some rising alternatives:
| Provider | Focus Area | Distinctive Feature |
| Skyscanner API | Flights + Metasearch | Real-time price tracking and alerts |
| Duffel API | Flights (NDC) | Modern RESTful APIs with airline directness |
| Kiwi API | Flights + multi-modal | Combines flights with ground transportation |
| TravelgateX | Accommodation + Services | Connects 1000+ suppliers via single API |
| Winding Tree | Blockchain-based travel | Decentralized inventory, lower fees |
Technical Challenges Ahead
While the travel API ecosystem expands, several issues remain:
Data Fragmentation
Each provider uses unique data structures, making aggregation complex.
Scalability
Many APIs struggle under high traffic, especially during peak travel seasons.
Security and Compliance
With GDPR, PCI DSS, and other regulations, APIs must ensure robust encryption and compliance.
Real-Time Synchronization
Ensuring accurate seat availability and pricing in real time remains a technical challenge.
Real-World Examples and Use Cases
Case 1: Duffel API in Modern Airline Booking
Duffel allows startups to build booking tools without traditional GDS contracts.
- Offers seat maps, baggage pricing, and fare families
- Used by startups like Lufthansa’s Sprk and Alternative Airlines
Case 2: Skyscanner APIs for Price Monitoring
Travel apps use Skyscanner’s APIs to monitor flight prices and send user alerts.
- Helps increase conversion by 17–22% (Skyscanner internal data)
Case 3: Winding Tree’s Decentralized Booking
Winding Tree powers blockchain bookings for hotels like Henn na Hotel in Japan.
- Reduces third-party commissions
- Supports crypto payments
What Developers Should Expect Next
The future will require more modular, cloud-native travel APIs.
Key expectations include:
- Open-source SDKs for quicker deployment
- GraphQL support for flexible queries
- Greater NDC adoption for airline integrations
- Built-in analytics APIs for trip behavior tracking
- Mobile-first documentation and sandbox environments
Recommendations for Travel Tech Businesses
To stay competitive in the evolving API landscape, businesses should:
- Continue Amadeus API Integration for global GDS access
- Explore secondary APIs like Skyscanner or Duffel for flexibility
- Test NDC-compliant APIs for direct airline content
- Use AI-powered APIs for personalization and recommendations
- Consider blockchain options for secure, decentralized bookings
Conclusion
While Amadeus API Integration remains critical, the future of travel APIs is increasingly diverse and dynamic. As new platforms emerge, businesses must evaluate which APIs align best with their operational goals, tech stacks, and customer needs.
Emerging trends like AI, NDC, blockchain, and real-time personalization are not just innovations—they are becoming necessities in a tech-driven travel ecosystem.
Travel companies that adapt early will be better positioned to offer responsive, transparent, and modern travel experiences in the years to come
Frequently Asked Questions (FAQs)
1. What is Amadeus API Integration?
Amadeus API Integration refers to the process of connecting travel platforms with Amadeus’ Global Distribution System (GDS) via its set of APIs. This enables access to flight schedules, hotel inventory, car rentals, and real-time booking capabilities.
2. Why are companies exploring alternatives to Amadeus APIs?
While Amadeus offers global reach, it can be complex to integrate, less flexible, and expensive for smaller agencies. New APIs offer direct airline connections, lower costs, modern architectures, and support for advanced use cases like NDC and personalization.
3. What are NDC APIs, and how do they compare with traditional GDS APIs?
NDC (New Distribution Capability) APIs, developed by IATA, allow airlines to deliver personalized content directly to travel sellers. Unlike traditional GDS APIs, NDC supports richer product offerings, dynamic pricing, and branded fares without GDS intermediaries.
4. How are AI and machine learning influencing travel APIs?
AI is enabling APIs to provide predictive pricing, smart itinerary suggestions, and real-time personalization. APIs powered by machine learning can analyze vast datasets to improve user experiences and optimize travel recommendations.
5. Are blockchain-based travel APIs practical for real-world use?
Yes, blockchain travel APIs are gaining traction. Platforms like Winding Tree offer decentralized booking, improved transparency, and reduced commission fees. While adoption is still early, real-world implementations by hotels and OTAs are increasing.
