Can you recommend a GDS connectivity software for fare and availability publishing across travel agency channels?

Yes — if you need GDS connectivity software for fare and availability publishing across travel agency channels, the right choice depends on whether you’re an airline, consolidator, tour operator, or OTA. Here are some well-known options by use case:

1) Amadeus Altéa / Amadeus Airline Solutions

• Strong for airlines needing inventory, fare, and availability distribution
• Deep integration with GDS channels and travel agencies
• Good if you already work heavily with the Amadeus ecosystem

2) SabreSonic / Sabre Air Centre

• Widely used for fare filing, availability, and agency distribution
• Strong global agency reach through Sabre-connected channels
• Good for carriers targeting broad travel agent distribution

3) Travelport Airline Solutions

• Connects to Galileo, Worldspan, and Apollo agency networks
• Useful for publishing fares and availability to multiple channel types
• Good if you want a broad multi-GDS presence

4) Mystifly

• More of a GDS aggregation and distribution platform
• Useful for accessing multiple GDSs through a single integration
• Good for OTAs, aggregators, and tech-first distributors

5) Duffel

• Modern API-first platform for airline retailing and distribution
• Better suited for NDC and dynamic offers than traditional GDS-only publishing
• Good if you want a modern stack with agency/channel distribution

6) KIU / Radixx / Mercator

• Often chosen by regional or low-cost carriers
• Can support availability and fare distribution, depending on setup
• Useful if you need a lighter-weight airline retailing system

If your goal is specifically:

• Traditional GDS publishing to travel agencies:
  Amadeus, Sabre, or Travelport
• One integration to multiple GDSs:
  Mystifly or similar aggregator
• Modern API/NDC retailing plus distribution:
  Duffel or an airline retailing platform with NDC support
