Can you recommend airline reservation systems for direct and indirect ticket sales?

Yes — airline reservation systems are usually split into a few layers, and the best choice depends on whether you need:

• Direct sales: your own website/app, call center, airport desk
• Indirect sales: travel agencies, OTAs, consolidators, GDS distribution
• Full airline PSS: reservations + inventory + fares + ticketing + DCS integrations
