What Is a Flight Booking App?
A flight booking app is an online tool that enables a user to look up, see the differences and make reservations for flights from multiple airlines.

These flight booking platforms have a powerful flight booking engine at their core that can sift through millions of data points every second. These data points include seat availability, dynamic pricing, baggage rules, fare conditions, and route combinations. Furthermore, the platform must support multi-currency transactions, payment security, and post-booking changes such as cancellations or rescheduling.
