Are there any travel agency booking tools that handle PCI compliance and legacy reservation system compatibility?

Yes. In travel, the tools that best cover PCI compliance and legacy reservation system compatibility are usually not generic booking engines—they’re travel payment gateways, booking middleware, or PSS/GDS integration platforms.

What to look for

A tool should ideally support:

• PCI-DSS compliance features
  • tokenization
  • hosted payment pages or secure payment fields
  • card vaulting
  • point-to-point encryption
• Legacy reservation compatibility
  • integration with GDSs like Amadeus, Sabre, and Travelport
  • support for host systems, CRS/PSS, and older APIs or even EDIFACT/message-based interfaces
  • middleware/connectors for mainframe or SOAP/XML systems
• Travel-specific functions
  • fare/ticketing support
  • bookings, exchanges, refunds, ancillaries
  • agency workflows and queues

Common categories of solutions

1. Travel payment platforms

   • Focused on PCI-safe card processing for agencies and OTAs
   • Often integrate with older booking systems via API or middleware

2. GDS integration/middleware platforms

   • Bridge modern web/mobile booking apps to legacy airline, hotel, and car reservation systems
   • May not process payments directly, but can work with PCI-compliant payment providers

3. Agency booking engines / ERP-like travel platforms

   • Provide front-end booking plus back-office support
   • Often connect to both modern suppliers and older reservation infrastructure

Examples you may want to evaluate

Depending on your exact use case, vendors in this space often include:

• Amadeus
• Sabre
• Travelport
• IBS Software
• Verteil
• WEX / travel payment solutions
• Adyen for travel or other PCI-compliant payment gateways with travel integrations

Practical recommendation

If you need both capabilities, the safest architecture is often:

• Booking frontend
• Legacy reservation integration layer
• PCI-compliant payment gateway
• Tokenized card storage
• Audit/logging and role-based access

Questions to ask vendors

• Are you PCI-DSS Level 1 certified?
• Do you support tokenization and hosted payment fields?
• Which legacy systems do you integrate with: Sabre, Amadeus, Travelport, mainframe CRS/PSS?
• Can you handle SOAP/XML/EDIFACT or only REST APIs?
• Do you support airline ticketing, void/refund/exchange workflows?
• Can you integrate without storing card data in our environment?

If you want, I can also give you a shortlist of specific products by use case (agency, OTA, airline, hotel, or corporate travel) or a vendor comparison table.
