US Domestic Airline Database (American Airlines)
American Airlines is the largest airline in the USA in terms of
revenue and passengers carried. With over thousands of
domestic flights carrying hundred-thousand of passengers daily,
database is the only sorting option. Hence, we are designing a
database that will capture all the information including
Airports, Employees and the Transactions among others.
Undoubtedly designing a database for an airline can become
complex, so we have added some limitations.
• We are assuming that each flight starts at source and ends
at destination without any intermediate stops.
• We are assuming that 1 booking can be made for only 1
person.
• There is no limit on baggage allowance.
• There is fixed airfare which depends on the route and class
of travel
• All flights scheduled have fixed departure and arrival time
with no delays.
• No pre-booking of seats allowed. Passengers are given
seat number at the time of check-in at the airport. Only
class of travel is preferred at the time of booking, no seat
number.
Data Requirements:
Aircraft:
•
•
•
•
•
•
Each aircraft has a unique number
Capacity (Number of seats) in the aircraft
Types of class available in the aircraft
Model type of the aircraft
Year of Manufacture of the aircraft
Manufacturing company
Here types of classes available in the aircraft depends on the
model type of the aircraft. Some aircrafts have all the classes:
First, Main Cabin Extra, Business and Main Cabin, while some of
them don’t. Database will have class wise capacity and total
capacity of an aircraft. Model Type depends on the
manufacturing company.
Airport:
• Each airport has a unique airport code defined by IATA
(International Air Transport Association)
• Name of the airport.
• City and the State where the airport is.
• One airport has multiple terminals.
Each airport has Ground Attendants and Administrative
Support.
Routes:
• Each flight route has a unique route ID
• Route’s source and destination airport
• Distance between source and destination airport
Flight is scheduled using the route.
Airfare:
• There will be a unique Fare ID for each flight route
• Class of travel and type of model
• Total fare in USD
Each route will be assigned the fare. Fare will vary depending
on the class preferred and model of the aircraft. So, a route can
have multiple fares based on class and model type of the
aircraft.

passengers. Each passenger has a unique ID, Name, Date
of Birth, Gender, Phone Number, Email ID.

also capture Name, Date of Birth, Gender, Phone Number,

multiple airports.

As each booking has the flight ID, it will help serve various
business goals of Airline. One Flight ID can be on several
bookings.
Business Goals:
• Airlines will get information regarding which route has
highest and lowest number of passengers by the bookings
and Flight schedule details.
• Airlines will get information regarding which airport has
most and least passengers travelling by bookings.
• Which class of travel is more preferred?
• We can figure out which time of the day is more preferred
by the booking details.
• We can figure out which day of the week is more preferred
by the booking details and the flight schedule.
• Database will help serve advertisement purposes for the
airline and the airline can also provide extra information
about the new features of airlines using the passenger’s
personal information.
