It is a dummy app designed to help the users find and book one-way flights to almost anywhere around the globe. The flights here were generated randomly and do not reflect real world data. The data on the international airports were scraped from this Wikipedia page.
This app makes use of some complicated data structures. It necessary to use the advanced form fields to represent the data properly in the front-end. The student will have lots of practice dealing with nested forms and dropdown menus while building this project.
