ANALYSIS

Based on my analysis from the three web sites which provided the service to booking the airline ticket, the result show that each system provide the good service for their customer but not all the services are efficient. From this analysis, I found that, customer who booking a ticket through Expedia need to type the origin and the destination that they are request. This situation can cause many problem occur in their system. Beside that, it is very difficult if the customer do not know the exactly name for the destination. So, the system can not process their request. Compare to the services provided in Malaysia Airlines and Air Asia, booth of these companies, provide the menu list of the place where they provide their flight service. So, customer can make their choice based on the listed place. So, easy for customer to booking the ticket and also give advantage for the system to process the request from the customer. Second aspect is about the organize of the content in the web pages. Expedia provide to much content in their web pages. This situation make their web pages look like very crowded and difficult for customer to read and classified which content is useful for them. Air Asia provide the simple content but easy to understand and also very meaningful for customer to get the exactly information they want. Malaysia Airline also provides the simple and meaningful content but it has so many pages but not all the pages have information. Some of the pages just 2

show the process happen at the moment. In my opinion, this pages is not important because the use of this page just increase the time for the system to loading faster. According to my analysis, only Air Asia provides the facilities about language for their customer. In my opinion, this method can attract the customer from many countries because not all the people from many countries understand English very well. This is a way for Air Asia to promote their service over the world through the attraction of languages. Beside that, Air Asia also gives the facilities for their customer to choose the seat based on the plan of the flight. This is one of the corporate promotions from Air Asia because customers feel free to choose their seat. Something interesting through Expedia is when customer search for the flight based of some requirements, the result can be sort base on price, time departure, duration and departure time. So, the customer has more choice to make a booking depend on their requirements. In this self-study, I found that, the time of process, the number of pages to complete a task, the number of the device switches and also the number of mouse clicks also can give an impact for user to use the service. All the three web sites is built to provide services for customer. So, the satisfied from the customer is very important. Customers do not like to waiting for a long time, want to finish the task in short term with a little bit pages, devices switches and so on. So, it is very important to analysis all of this element before any web pages or interface was built.

RECOMMENDATION

In my opinion, these three web sites should minimize the web pages for ticket booking process because the time to process many web pages will decrease and customer will be more comfortable to use the service. I think, the loading process should be hiding from the user because when the web pages that show the process on loading appear, it will increase the time for the processing to be done. Beside that, the using of message box is better than the web pages to tell the customer if any error happens or any process was done. My second recommendation is, each web sites should avoid from using to much text field which requires input from user in the important case like destination or origin because if the customer put the wrong input, the process will not be done. It is better if the web sites use menu drop down or menu list.
