What is Flight Booking Engine?

A Flight Booking Engine is the core technology module that powers the flight search, availability, pricing and booking workflow on a travel portal. It connects your website in real time to one or more airline APIs or Global Distribution Systems (GDS), retrieves live flight schedules and fares, and enables end-to-end booking — from search to confirmed PNR and e-ticket delivery — without any manual intervention.

UP17 Communication's Flight Booking Engine is a standalone, API-driven module that can be integrated into any existing travel website or deployed as part of a full B2C or B2B portal. It supports domestic and international flight bookings across all major Indian carriers (IndiGo, Air India, SpiceJet, Vistara, AkasaAir) as well as international full-service and low-cost airlines worldwide.

The engine connects to TBO.COM, Amadeus, Sabre or Mystifly — whichever API you hold access to — and handles the complete booking lifecycle: search, fare rules retrieval, seat selection, ancillary add-ons (meals, baggage), booking, payment, e-ticket generation, and post-booking services (cancellation, date change, refund processing).

Speed is a critical metric for flight booking. Our engine uses asynchronous API calls, intelligent caching of recently searched routes, and a fast-loading AJAX search results page to deliver sub-3-second search results even on mobile connections. The calendar fare display and price graph help customers find the cheapest travel date, increasing conversion rates significantly.

Key Features

Everything you need to run a successful Flight Booking Engine business.

One-Way, Round-Trip & Multi-City Search
Full-featured search form supporting one-way, return and multi-city (up to 6 legs) itineraries. Class selection (economy, premium economy, business, first). Passenger count (adult, child, infant). Advanced search filters: airlines, stops, departure time, duration and price range.
Real-Time Availability & Pricing
Live API calls fetch current availability and the lowest available fares for the requested route and date. No static cache for fares — every search is a fresh API call to ensure accurate pricing. Fare family display shows the rules for each fare (refundable, non-refundable, change fee).
Flexible Date Calendar
Interactive calendar showing the fare for every date within a 30-day window. Colour-coded by price range — customers can instantly spot the cheapest day to fly. Price trend graph shows historical and forward pricing for informed decision-making.
Seat Selection & Ancillaries
Interactive seat map (when supported by the airline API) lets passengers choose their preferred seat during booking. Add pre-paid baggage, meal preferences and priority boarding at the booking stage — fully automated with the airline system.
PNR Generation & E-Ticket Delivery
On successful payment, the engine creates the booking with the airline and retrieves the PNR (Passenger Name Record) or Booking Reference. A formatted e-ticket is auto-generated as a PDF and emailed to the passenger. Web check-in links are included in the email.
Cancellation & Refund Management
Full online cancellation workflow with airline-specific penalty calculation. Partial cancellation (one passenger or one leg) supported. Refund is processed to the original payment method automatically. Refund status tracking available in the customer dashboard.
Markup & Convenience Fee
Apply fixed or percentage markup by airline, sector, booking class or departure airport. Add optional convenience fee at checkout. Corporate discount codes and promotional fare overrides configurable through the admin panel.
Mobile-First Search Interface
The search and booking flow is optimised for mobile — large tap targets, sticky CTA buttons, swipeable fare comparison cards and fast page loads. Works seamlessly on 3G/4G connections, making it accessible to travellers across Tier 2 and Tier 3 cities.
Multi-GDS / Multi-API Support
Connect multiple API sources simultaneously (e.g., TBO for LCC fares and Amadeus for full-service carriers). The engine combines results intelligently, removes duplicates, and displays the best available fare per routing — giving your customers the widest choice.
GST-Compliant Invoicing
Auto-generate GST invoices with correct SAC code (9964) for air travel services. CGST/SGST or IGST applied correctly based on customer and company GSTIN. Invoice downloadable by both customer and admin. Monthly invoice report for GSTR filing.

Why Choose Flight Booking Engine by UP17?

We build enterprise-grade software tailored for the Indian market.

Highest Fare Accuracy Available
By connecting directly to airline APIs and GDS systems, our engine retrieves live pricing — not outdated cached fares. This means fewer booking failures, fewer price-difference errors, and a better experience for your customers.
Increases Your Average Order Value
Built-in ancillary upsell (baggage, meals, seat selection, travel insurance) adds revenue per booking without any additional sales effort. Customers who add ancillaries have lower cancellation rates and higher satisfaction scores.
Reduces Operational Workload
With automated PNR generation, e-ticket delivery, cancellation processing and refund calculation, your team handles exceptions only. Most bookings complete from search to e-ticket without human involvement.
Integrates with Any Portal
The flight engine is built as a modular component — it can be added to an existing travel website, CRM or ERP without rebuilding the entire platform. REST API endpoints available for custom front-end integrations.
Competitive Advantage Through Speed
A fast, responsive booking experience is one of the top factors customers cite in choosing a booking platform. Our AJAX-based search results and optimised API handling deliver industry-leading page load times.

Frequently Asked Questions

Got questions? We've answered the most common ones below.

TBO.COM (Travel Boutique Online) is the most popular choice for Indian travel portals — it covers all domestic Indian carriers and 500+ international airlines, and API access is relatively straightforward to obtain. Amadeus and Sabre are alternatives favoured by IATA agents. We can integrate whichever API you have (or help you apply for access).
We do not provide API credentials — you need to apply to TBO, Amadeus or your preferred provider directly. However, we guide you through the application process and handle the full technical integration once your credentials are issued.
Yes. International flight search, booking, e-ticket generation and post-booking services (visa requirements, baggage policies, transit information) are fully supported. The engine displays prices in the currency of your choice with an auto-conversion rate.
The engine includes a booking-failure handler: if payment is collected but the airline booking fails (due to seat sold out or API timeout), the payment is automatically refunded via the payment gateway and the customer is notified by email and SMS. All failed bookings are logged for admin review.
Yes. The e-ticket template is fully customisable with your logo, brand colours, contact details and any custom footer text. Customers receive an e-ticket that looks like your company issued it — not the airline or the API provider.
Absolutely. There is no minimum booking volume requirement. The platform scales from zero — you pay no per-booking fee to UP17 (though your API provider may have their own fee structure). Start small and grow without re-platforming.
