What to look for

If you mean “channel management” in the hotel sense, airlines usually use a mix of:

• GDS distribution
• NDC/API distribution
• Direct web/mobile sales
• Corporate/agent portals
• Interline/partner sales
• Ancillary/offer management

So the best-fit platform depends on whether you need:

• distribution connectivity
• booking and reservation management
• offer/order management
• retailing and ancillaries
• pricing and revenue optimization
