Most of the airlines get thousands of cvīs. They can literaly swim in them. Now if you do not have a friend to put you at the top of the pile it gets really hard to attract attention. The only thing you have going for you might be experience, so make sure that is on there and easily findable. If you are young and have not much job experience you can fill it with some jobs done during studying time. But as soon as you get one or more serious jobs throw them out. You did not take a job at 16 serious and neither will they.
Leave out irrelative information. They already know that you where born and donīt care where for instance. Also this is not the place to start about your personal qualities such as leadership, social skills, etc etc. Put this in your applying letter which is far more important when it comes to getting that interview. A cv should be for all companies you apply to the same. However a letter you should perferably write custom made for the company where you are applying. FInd out what is important to them (usually available on website, search for company mission statement and such). And make sure you include those as some of your finest qualities. DO NOT write one letter and then copy paste the adress of a zillion companies. They know these letters and will throw them out. I have talked to guys saying they applied to over 100 companies and did not get one single reply. Offcourse not if your letter does not show commitment (and they did not qualify for half those companies).
Good luck mate.
