Travel Portal

Travel portals can be roughly divided into two distinct business classes, each catering to a different audience, with the software architecture specific for each type.

1. B2C (Business-to-Consumer) Portals

These are public-facing online travel agencies (OTAs) like Expedia, Booking.com, or Skyscanner.
Their mission is to provide a smooth user experience, speed, and high conversion rates. The key tech includes highly scalable search caching (so that they can withstand high loads), localized payment gateways, public review systems, and retail marketing functionality such as countdown timers and cross-selling widgets.

2. B2B (Business-to-Business) Portals

These are password-protected private networks for either a travel agency, a corporate travel department, or a wholesaler.

Their objectives are profit maximization, agent network management, and adherence to strict compliance. The key tech encompasses complex business rules engines for agent-specific commissions and markups, multi-tiered access control (admin vs. regular agent), and a mid-office system for offline queue processing and invoicing.

The architecture of a powerful travel portal resembles a three-layer cake:

• Front End (UI/UX): This is the visual interface where the traveler or agent enters dates, destination, and filters and views the returned results.
• Internet Booking Engine (IBE): Being the functional heart, the IBE receives the search criteria entered on the front end, converts them into XML/JSON requests, sends in parallel to multiple supplier APIs, merges the results to remove duplicates, and returns the results to the user.
• Back-Office/Mid-Office: It is an administrative control panel. This is where the travel portal owner is going to set pricing rules, gain visibility on real-time sales reports, track supplier payouts, and manage cancellations/re-bookings.
