Installation

Install the module via npm:

npm install flight-ticket-module-mearn-r2

How it Works

1. Import the FlightTicket class from the module.

2. Create a new instance of FlightTicket.

3. Use createTicket() to initialize ticket information.

4. Access or modify ticket data using the available methods.

5. Display ticket information using displayTicket().

All updates are validated and private properties prevent direct manipulation of internal data.
