1. Introduction
First Class Airlines (FCA) was founded in 1999 and provides flights to an elusive clientele of elite corporate executives and government employees. They are known for their very high level of service with all of the conveniences of the office to ensure that transportation from one city to another is not a disruption to their clientele’s workload. To book a flight with FCA, one must call into the FCA central office to reserve a flight and make any special requests. A service that was once a little known secret in the corporate world is beginning to grow. As a result, FCA is struggling to keep up with the demand for their service. To combat this struggle, FCA purchased 50 additional passenger planes and hired of 300 new employees; however, customers are still frustrated by the long wait times experienced when scheduling flights by phone. As a result, FCA has hired Lewis Consulting to create and implement an Airline Reservation System (ARS) that will be accessible as an application for the Samsung Galaxy S6 smartphone.
This Software Requirements Specification (SRS) outlines the steps taken to create a working solution for the initial deployment of the FCA reservation system. The role of Lewis Consulting will be to design and implement an ARS that can be used by passengers and potential passengers as a self-service tool. Phase 1 of the FCA Reservation System will allow passengers to establish a secure connection to the FCA Reservation System, log in, search for available flights, create a reservation, cancel a reservation, and view a listing of all reservations.
Main topics are bolded in a heading and are represented using whole numbers. Sub topics and bullets are indented beneath the main topic heading with a decimal version of the whole number. All acronyms will be introduced with its full name, followed by its acronym in parenthesis. From this point forward, the acronym is used in place of the full word titles. In the glossary in Appendix A, any acronyms used within this document are outlined in alphabetical order for easy reference.
This document is written by Lewis Consulting in response to FCA’s request for a proposal for the first phase of the ARS. It is intended for use by all who are involved in the design of the FCA Reservation System. This includes all stakeholders and employees of FCA, in addition to designers, developers, testers, programmers, testers, and programmers of Lewis Consulting Services. This document is best read from beginning to end to fully grasp the program to be implemented, however the table of contents can be used to hone in on specific areas of interest to specific readers. By using the CTRL key and clicking on any item in the Table of Contents, readers can jump straight to topics of interest.
This document is not intended for use by end-users. Documentation provided for use of the software by end users should be created by FCA after the completion of this application.
In the first phase of FCA Reservation System, the following functions will be included:
Establish a secure connection Login to the system Search for available flights Create reservation View reservation Cancel reservation
The ARS will be accessible from all the Samsung Galaxy S6 smartphone with the FCA Reservations Application installed. Lewis Consulting will perform one User Acceptance Test (UAT) with FCA representatives.
Training of FCA Reservation System users and managing login credentials is out of the scope of this project and is the responsibility of FCA.

2. Overall Description
The FCA Reservation application is a brand new venture for FCA. As a small airline, there are concerns that the application may not compete well with those of larger scoped travel applications, like Travelocity and Expedia. The goal with Phase 1 of the FCA Reservation application is to offer travelers the ability to provide basic flight searching, reservation and cancellation abilities from the Samsung Galaxy S6 smartphone. The desired result is a product that allows flyers to self-serve and avoid long telephone hold times when calling into the FCA Reservation office.
Figure 2.1 – Samsung Galaxy S6 smartphone
The FCA Reservation application allows users of the Samsung Galaxy S6 smartphone to install the application from the Google Play Store and perform a series of actions to aid in the airline reservations process. These functions include securing a secure connection to the FCA Servers, logging into an account, searching for flights, creating a reservation, viewing all reservations, and cancelling a reservation.

Users of the application are knowledgeable about using applications on their Samsung Galaxy S6 smartphone. Users will keep the FCA Reservation application and smartphone updated It is the responsibility of FCA to keep the application updated with the most current technology The servers at FCA are up and running.
3. System Features
This section outlines the low level details of each system function of the FCA Reservation System. It sets priorities of each function so that developers and FCA stakeholders know what will be accomplished first and what functions will be available for review first.
3.1.1 Description and Priority Because sensitive information and personal data is exchanged between passengers and the application, the information contained within each session must remain protected and confidential. FCA is responsible for safeguarding the data transferred by the FCA Reservation System application. It is crucial that the FCA Reservation System application keep this data encrypted and safeguarded from those with nefarious or malicious intent. This is the highest priority.
3.1.2 Stimulus/Response Sequences The user opens the FCA Reservation application by touching the application icon on their Samsung Galaxy S6 smartphone. This launches the application interface and automatically begins securing a connection to the FCA servers. 3.1.3 Functional Requirements SS-1: a secure session is established between the FCA Reservation application and the FCA servers SS-2: an icon displays to let the user know that a secure connection has been successfully attained prior to continuing to the rest of the application SS-3: if a secure connection could not be established, an error message is displayed and the application closes SS-4: when the application is closed or when 5 minutes of inactivity elapses, the secure session terminates
3.2.1 Description and Priority The user will be prompted by the FCA Reservation application to enter a username and password on a login screen. Upon submission of valid login credentials, the data will be verified by the FCA Servers. Verification of the user is important because the Samsung Galaxy S6 smartphone may be lost or accessed by someone other than the authorized user. Because this application includes payment data and other sensitive materials, ensuring that only authorized users can access this data is crucial. Passengers and FCA is responsible for the protection of login credentials. This feature is of highest priority.
3.2.2 Stimulus/Response Sequences After a secure session is established, a login screen will be displayed to the user. The user will enter a username and password, and then select a button that says, “Login” to submit their credentials to the FCA Servers for validation. The application will display a message indicating the success or failure of the authentication. 3.2.3 Functional Requirements LI-1: a login page is displayed and asks the user to enter a username and password. LI -2: the password will be masked as it is typed into the login interface LI -3: a touchable button submits the username and password from the login form to the FCA Server LI -4: the credentials are compared against those stored in the FCA database LI-5: if login information does not match, the user will be given two more chances to enter correct login information LI -6: after 3 failed login attempts, the user account is locked and an error message is displayed instructing the user to call a 1-800 number to reactivate the account LI-7: if the database matches the credentials, the server returns the confirmation LI-8: after confirmation of correct login credentials, the FCA Reservation application menu is displayed
3.2.4 Test Case 1: Failed Login Lockout Test Name: TC1: Failed Login Lockout Description: User is locked out after 3 failed password attempts Requirement(s): Spec. 3.2, LI-1 – LI-6 , UC Prerequisites: The FCA Reservation has been installed on a Samsung Galaxy S6 smartphone. Setup: The user will begin by opening the FCA Reservation application from a Samsung Galaxy S6 smartphone. The application interface will indicate through imagery that a secure session has been established with the server.

SF-2: a touchable button submits the data SF-3: data is validated for completeness, accurate dates, and valid cities of departure and arrival SF-4: if the data is complete and valid, the FCA Reservation application will request matching flights from the FCA database SF-5: if matching flights exist, the FCA Reservation application will display matching flights to the user SF-6: if no matching flights exist, an error will be displayed and nearby cities of departure/arrival will be presented to the user
3.3.4 Test Case 2: Search for Flights Test Name: TC2: Search for Flights Description: Display flight listing Requirement(s): Spec. 3.3, SF-1 – SF-5, UC Prerequisites: The FCA Reservation has been installed on a Samsung Galaxy S6 smartphone. The tester has valid login credentials. Flights must exist in the database that match the criteria that the tester will be entering. Setup: The tester will begin by opening the FCA Reservation application on a Samsung Galaxy S6 smartphone. The application interface will indicate through imagery that a secure session has been established with the server. The user will log into the application with valid login credentials, and then select “Search for Flights” from the application’s main menu.

3.4.1 Description and Priority After selecting an available flight, users can create a reservation for a flight. Users will then submit their personal data to secure their seat for the flight. Because this function is a main motivation for the creation of the FCA Reservation Application, but is not as crucial as the establishment of a secure session or login, its priority is medium. 3.4.2 Stimulus/Response Sequences After an available flight is selected, the FCA Reservation application displays a reservation form. Upon submission, the FCA Reservation application submits the payment details to the Pay Processor and all other fields to the FCA Database. For entries with successful payment, a reservation will be created and confirmation will be provided to the user. For payment failures, a reservation will not be created and an error message will be displayed to the user. 3.4.3 Functional Requirements CNR-1: display a reservation form to users to enter their name, email address, and billing information CNR -2: a touchable button submits the data CNR -3: data is validated for completeness CNR -4: if data is missing, an error message is displayed CNR -5: if data is complete, the FCA Reservation application will submit the user’s name and email address to the FCA Database for storage upon selection of the submit button CNR -6: if data is complete, the FCA Reservation Application will submit payment information to the Pay Processor for processing upon selection of the submit button CNR -7: the FCA Reservation Application will display a success or failure message provided by the Pay Processor CNR -8: if the payment is successful, a confirmation message will display on- screen and be sent to the email address provided by the user CNR -9: if the payment is not successful, an error will display and up to two additional attempts will be permitted CNR-10: after three failed payment attempts the user will be prompted to call a 1- 800 number to complete their reservation

A loading symbol appears. The application resends a request to the FCA server/database for the individual reservation details.
3.6.1 Description and Priority Users who have previously made a reservation can cancel a reservation for flights scheduled to depart more than 72 hours in the future. This functionality is not core to the vision of the application as a whole so its priority is low.
3.6.2 Stimulus/Response Sequences A user who has a confirmed reservation selects “Cancel Flight”. For flights scheduled to depart within 72 hours, the user is given an error message instructing him or her to call FCA to cancel their flight. For flights scheduled to depart more than 72 hours in the future, the FCA Reservation application instructs the Pay Processor to refund the reservation fee and instructs the FCA database to update the reservation from a status of RESERVED to a status of CANCELLED. An on-screen notification and email notification are provided to the user upon successful cancellation of the reservation. 3.6.3 Functional Requirements CR-1: the FCA Reservation application will prompt the user to confirm that they would like to cancel the reservation before taking action. CR-2: for flights scheduled to depart within the next 72 hours, an error message will display to prompt the user to call a 1-800 number to cancel CR-3: for flights scheduled to depart 72 hours or more in the future, the FCA Reservation application will instruct the Pay Processor to issue a refund of the reservation fee
CR-4: for flights scheduled to depart 72 hours or more in the future, the FCA Reservation application will update the reservation status for the user from RESERVED to CANCELLED CR-5: an on-screen confirmation of refund and cancellation will be provided to the user
