Air Booking allows you to build what most Online Booking Engines do; book a trip with flights for a given traveler:
Step 1: Search for flight options by lowest fare via Bargain Finder Max.
Bargain Finder Max computes a vast array of airline schedules and fares across multiple dates to assemble the best set of itinerary offers within seconds.
Step 2: Revalidate the availability and pricing for a specific itinerary option with Revalidate Itinerary (without actually booking a flight).
This API can also be used to request additional information about rules, flight details, and seating, including upselling to other options.
Step 3: Generate an entire reservation (PNR) within a single API by using Create Passenger Name Record.
This API books all flights, prices and stores fares, and adds all necessary data/special requests (if any) within a single API call.
