I'm creating a website for a travel agent. She wants to include a feature where she can let the user book a flight or cruise(especially this) from her website via an API. I would prefer a free API that provides this functionality, but I am willing to look at quality commercial API's if they offer the services I need.
Here are some I have already found(but I am not sure if they do what I need):
Free
- Cleartrip API - http://www.programmableweb.com/api/cleartrip
- Vianet API - http://www.programmableweb.com/api/vianet
Commercial
- AgentFactor Travel API - http://www.programmableweb.com/api/agentfactor-travel
- Rezgo API - http://www.programmableweb.com/api/rezgo
- TravelFusion API - http://www.programmableweb.com/api/travelfusion
- TravelPort API - http://www.programmableweb.com/api/travelport
Does anyone know any other API's/services(free & commercial) that can help me do what I need? If any of the above API's I mentioned does what I need and you recommend that, please tell me which one and why. Thank you.
