Frequently Asked Questions

What is a flight booking PHP script?

A flight booking PHP script is the backend and UI layer that lets customers search flights, price itineraries, take payment, create a booking, and issue an e ticket on your own website. In production it typically includes offer shopping, fare rules, baggage details, traveler validation, booking confirmation, ticketing, emails, and an admin panel to manage changes and refunds.

Is PHPTRAVELS open source?

Yes. The platform is built in PHP with an editable HMVC structure, so your developers can customize the flight search UI, business rules, markups, currency behavior, and integrations. You keep code control while still getting support and updates, which reduces long term maintenance risk versus building from zero.

Which GDS and flight APIs are supported?

PHPTRAVELS supports Amadeus, Sabre, and Travelport out of the box through adapter based integrations. This covers core flows like search and pricing, fare rules, PNR create and retrieve, ticketing, and post booking operations such as changes and refunds depending on the supplier scope you have enabled.

Can I build and test without a GDS contract?

Yes for development and QA. You can use sandbox credentials where available, or run mocked responses to validate your UI, pricing logic, and checkout flow. When you are ready to go live, you switch to production credentials, enable ticketing, and run certification steps required by your supplier.

Where do I store PNR and e ticket numbers?

PNR and e ticket numbers are stored in your bookings and ticketing tables so your system can support post booking servicing. Best practice is to store PNR, ticket number, fare basis, baggage allowance, supplier reference, and timestamps for hold, confirm, and ticket issuance, so support teams can reconcile and handle changes reliably, and power a flight status and tracking page for travelers.

How do I prevent duplicate bookings and double charges?

Use idempotency keys on payment and booking create calls and enforce uniqueness in the backend. The safe flow is price revalidation before payment, then authorize or capture, then booking create, then ticketing. If any step fails, your system should safely retry without creating a second booking or charging again.

Do you provide a sample widget or Postman collection?

Yes. We can share a sample flight search widget and a Postman collection for the main endpoints such as shopping, repricing, booking, and ticketing. This helps your team test integrations faster, validate payloads, and debug issues with consistent request templates.

How fast is search and how reliable is uptime?

Search speed depends mainly on supplier response time, routing, and your caching strategy. In most markets you can target a fast first result experience by using smart filters, timeouts, retries, and caching where allowed. For reliability, production setups use monitoring, rate limit handling, circuit breakers, and clear fallback messaging to maintain a stable booking flow.
