The functionality is the interactive part of the site that to respond in some way. All the website should work properly. The user expects each link to be valid. Broken links on the web page always downgrade the quality of the website [3]. A website without reet. It is pointless to have a website that does not provide any form of visitor interactivity. The second factor is reliability; it is difficult to define the term objectively. Website reliability is the probability of failure-free operation of the website within a specified environment for a specified purpose. In the other hand reliability is ameasure of how well the users perceive a website provides the required services. For each failure identified, describe the acceptable reliability using an Appropriate metric. Next efficiency, it means more Effective design and simple process of digesting information on a website. Today's web users are sophisticated and they know that there are plenty of other websites available to fulfil their needs. Leaving unfulfilling website is the first line of defence when someone encounters the slightest difficulty. A website server should respond to a browser request within certain parameters. The Skytrax rankings are based on the impressions of 19.87 million travellers from 105 different countries. Business Insider 2016 [4] reported that Skytrax world airline star rating is the recognized global airline rating system that classifies airlines by the quality of their service. The survey, which covered more than 325 airlines, measured 49 parameters ranging from the quality of service. Table-1 showed the ranking of airlines based on report publishes by London based consultancy firm Skytrax in 2017. The usability of a website is one of the most important factors that make or break the site. User -centric design has become the standard approach for successful and profit-focused web design. If airlines website home page fails to clearly state what a company offers and what users can on the site, people often leave the site. If users get lost on a website, they will probably get frustrated and leave. Portability means the ability to move the website from one Host Company to another and the platform that runs the site will work on the new host. If a web company builds the site on their own proprietary platform and the platform itself is not transferable, then the website would not work properly if the user tries to move it somewhere else. Maintainability is not an initial development, but in its on-going maintenance, fixing bugs, keeping its system operational, investigating failures, adapting it to new platforms, modifying it for new cases, repaying technical debt, and adding new features [5]. Figure-1 shows the various factors of website quality.

Background of the Study
The website evaluation, most studies focus on the factors for successful websites based on the user's perspective. These studies search for design and content elements of a successful website using the exploratory study. The main areas of the website quality evaluation are functional, usability, efficiency and reliability [6]. Website architecture is classified into two main areas which are content and design [7] and each category is specified into evaluation criteria according to the characteristics and perception of a website.
The website evaluation model is based on the study of the user-centered development and evaluation approach. Best websites selected by experts and users are investigated in order to identify the common characteristics of them The criteria include structure, content, navigation, visual design, functionality and interactivity. The new methodology which is Web Tango introduced in the previous study. It is a website quality check tool, which proposes to help non-professional designers to develop their sites using quantitative measures of the website [8].
An automated website evaluation tool is developed by applying the software quality. The function of an automated website evaluation tool consists of capture, analysis and critique of website data [9]. This tool is widely used in practice and some Broken links can give bad impact for the credibility of a website. Credibility is especially important in the World Wide Web, because transaction between customer and seller is not on the spot and the risk of fraud is several times higher. The customers would certainly choose to buy from a website that looks professional [11].  and German (www.lufthansa.com). The airlines' websites were selected based on the result of a survey conducted by Skytrax Company.

Analytical hierarchy process
Analytical hierarchy process (AHP) is a structured technique for organizing and analyzing complex decisions, based on mathematics. It was originally designed by Saaty [12] to solve complicated multicriteria decision problem, beside that AHP is appropriate whenever a target is obviously declared and a set of relevant criteria and alternatives are offered. AHP has been proposed for determining the best website to support researcher through the decision-making activity, which aims to determine the best website among a pool of airlines website. AHP is a popular model to aggregate multiple criteria for decision-making [13]. In AHP, the problems usually presented in a hierarchical structure and the decision-maker is guided throughout a subsequent series of pairwise comparisons to express the relative strength of the elements in the hierarchy.
In general, the hierarchy structure encompasses of three levels, where the top level represents the goal, and the lowest level has the website under consideration. The intermediate level contains the criteria under which each website is evaluated. In the constantly fluctuating of the website, the evaluation cannot survive without comprehensive quality factor identification and evaluation. The AHP methodology is demonstrated by applying it to the quality factors with the airlines website problem. Construction of the hierarchy is the first step in the problem-solving process.

Fuzzy analytical hierarchy process model (FAHPM)
In spite of the popularity of AHP, this method is often criticized for its inability to adequately handle the inherent uncertainty and imprecision associated with the mapping of the decision-maker's perception of exact numbers [14]. Since fuzziness and vagueness are common characteristics in many decision-making problems, a fuzzy AHP (FAHP) method should be able to tolerate vagueness or ambiguity [15]. In other word the conventional AHP approach may not fully reflect a style of human thinking because the decision makers usually feel more confident to give interval judgments rather than expressing their judgments in the form of single numeric values and so FAHP is capable of capturing a human's appraisal of ambiguity when complex multi-attribute decision making problems are considered [16]. This ability comes to exist when the crisp judgments transformed into fuzzy judgments. Zadeh [17] published his work Fuzzy Sets, which described the mathematics of fuzzy set theory. This theory, which was a generalization of classical set theory, allowed the membership functions to operate over the range of real numbers [0, 1]. The main characteristic of fuzziness is the grouping of individuals into classes that do not have sharply defined boundaries [18]. The uncertain comparison, judgment can be represented by the fuzzy number. A triangular fuzzy number is the special class of the fuzzy number whose membership defined by three real numbers, expressed as (l, m, and u). The triangular fuzzy numbers are represented as follows Figure.3.

Figure3. Fuzzy triangular number
In this case, the goal of an AHP and the also FAHP decision is to select the best airlines website during the first level. Load time, response time, page link, frequency of update, traffic, and design, and size, number of items, accessibility error, markup validation and broken link are the evaluation criteria during the second level of the hierarchy.

Result and Discussion
The result of the website quality test based on load time, response time, page rank, frequency of update, traffic, design optimization, size, number of times, accessibility error, mark-up validation and broken link are also displayed in Table-3.

Conclusion
In this paper, the author evaluates the quality of international airline websites with sample of five airways namely, Qatar airways, Singapore airlines, emirates airways, Cathay pacific airways and Lufthansa airlines. Examined many dimensions of quality, and each dimension has been measured by specific test using a series of online diagnostic tools. The result of this study confirmed that more effort is required to meet with these criteria in the context of website design. The author proposed fuzzy analytical hierarchic process model as a methodology for determining and evaluate the best airline website based on many criteria of website quality. Regarding the final results, the website which has the highest score is suggested as the best website for the proposed FAHP model. The study result suggests that web designers responsible for airlines website should follow and encourage the use of recognized guidelines when designing a website.
