Technical integration & business model of travel portals:
For integration and automation of booking and ticketing processes along with real-time access to flight details, Airline Reservations System (ARS) was evolved. Most of the travel portals use GDS (Global Distribution Systems) like Amadeus, Abacus and Galileo etc. - They provide access to full-service airline systems for fare/availability. These GDS companies have developed their own Web interfaces, and now sell their services directly to consumers ( online travel portals). The travel portals also have to register with IATA in order to do ticketing and settlement. Additionally, they register as an agent with low cost carriers and negotiate with the airlines for commissions and bonuses. Online advertising and commissions on ticket bookings is the main source of revenue for these travel portals. So which portal is the best ?? Well its a personal choice and experience. Here is my personal favourites in each category : Airlines, trains and bus ticket bookings:
