If you've no idea which airline might fly from Yerevan to Adler, this is a good place to start. Comprehensive flight schedules for over 400 airlines. Note that Amadeus' coverage for budget airlines is patchy. Air Berlin flights, for example, are included. But flights by EasyJet are not. _

What's new in European aviation? This site carries a useful overview of new routes and airlines. Not always bang up-to-date, but still worth the occasional look. _

Amazing! Much, much more detailed that CH-Aviation (see link above), but with a less exclusively European focus, the Luchtzak website is a good place is keep abreast of what happening in the world of civil aviation. _

Useful listings of who flies where. But far from comprehensive, for the emphasis here is very much on low-cost carriers. However, still useful, particularly if used in connection with Amadeus (see above) which is good for traditional airlines but patchy on low-cost carriers. _
