The rapid changes taking place on the World Wide Web (WWW) and at many Internet makes producing a useful list something of a challenge as new sites are springing up all the time. Most existing airlines (and some from the past!) have other web sites set up by the company themselves or by enthusiasts. It is usually fairly easy to tell them apart.
The list of site addresses given below is split into two main categories - actual sites of companies and sites that provide access to many other relevant sites from a menu. Once you had found a useful site remember to use the "Bookmark" facility in Netscape to mark the page for easy future reference.
