Airplane booking system

Our company needs to add an airplane booking system to the current application. Currently the fleet is composed only by a short range plane that has the following characteristics:

{
	"aircraft_type": "short_range",
	"sits_count": 156,
	"rows": 26,
	"row_arrangement": "A B C _ D E F"
}

Requirements:

Create a REST API that supports a multiple-seat booking, expecting the passenger's name and the number of seats to book (up to 7). As a result, it should return the positions of all seats reserved.

Constraints:

• If passengers can all fit in a row, the system will book them in the same row. (ex. ['A1', 'B1', 'C1'] or ['E1', 'F1'])

• If passengers don't fit in a row without crossing the aisle, the system will balance them across rows. (ex. ['A1', 'B1', 'A2', 'B2'])

• If there are no available seats and the seats cannot be arranged all across rows, they will be booked to be nearby across the aisle. (ex. ['C1', 'D1', 'C2', 'D2'])

• If none of the above rules are appliable, the system will position passengers in a random seat.

• The booking should start from the window seats, when possible.

Example:

Bookings:

• Marco: 4 people;
• Gerard: 2 people; Result:
• Marco seats: 'A1', 'B1', 'A2', 'B2';
• Gerard seats: 'E1', 'F1';

Bookings:

• Iosu: 2 people;
• Oriol: 5 people;
• David: 2 people; Result:
• Iosu seats: 'A1', 'B1';
• Oriol seats: 'D1', 'E1', 'F1', 'E2', 'F2';
• David seats: 'A2', 'B2';

Bookings:

• Iosu: 2 people;
• Gerard: 2 people; Result:
• Iosu seats: 'A1', 'B1';
• Gerard seats: 'E1', 'F1';

You should:

• Write unit tests!
• Add information about your design decision.
• Write a production-ready code.
• Design the code to be extensible.
• Suggest possible enhancements.
• Provide the source code with all the git history and the description of how to execute the code.
• Feel free to use docker to simplify the execution process.
