SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

The Journal of Air Transport Management (JATM) sets out to address, through high quality research articles and authoritative commentary, the major economic, management and policy issues facing the air transport industry today. It offers practitioners and academics an international and dynamic forum for analysis and discussion of these issues, linking research and practice and stimulating interaction between the two.
The refereed papers in the journal cover all the major sectors of the industry (airlines, airports, air traffic management) as well as related areas such as tourism management and logistics. Papers are blind reviewed, normally by two referees, chosen for their specialist knowledge. The journal provides independent, original and rigorous analysis in the areas of:
• Policy, regulation and law
• Economics and finance
Papers are welcomed covering key industry developments and trends, such as changes in government thinking towards air transport; evolving competitive environments and new industry structures; emerging and maturing markets and changing customer needs; sustainability and security challenges; and industry innovation and technological developments.
In addition to normal papers, JATM also contains 'Notes' articles. These are short articles not exceeding 2500 words in length (including any references, footnotes, tables and figures). They should be self-contained papers, of either a theoretical or applied nature, that provide a stimulating approach to address a major and topical management or policy issue. They should not be review papers, indeed lengthy reviews of previous work should be avoided, and instead notes should succinctly address the topic in hand. The notes are subject to the normal blind refereeing process to maintain the high standards of the journal.
