I am deeply impressed - very fast answers
Delyan, thanks for your hint but I already knew the Air Via website. unfortunatly they are only talking about some stuff for passangers (by the way, is there no bulgarian version of this carrier???). Unfortunatly I couldn´t find any facts about some plans concerning the future of their fleet.
I´ve started this topic because I remember Air Via offered a weekly flight from Sofia to Berlin every saturday until the end of march. but shortly after I found the article about the GWPS I checked the flightplan again and suddenly the Air Via flight to Sofia was offered only until the end of january. a consequence of these new rules? if so, what a shame. I really like them.
I am a bit afraid that the new laws (noise restrictions and other new rules) might be the "end" of many airlines using russian airliners. specially the russians will have a lot of problems. and in consequence some german airports like Hannover (for example this summer there were weekends with up to 40 tupolevs and more!!!) might have problems too because I doubt it will be possible to replace these birds in just a few months.
anyway, I think Bulgarian airlines are well known in Germany. But specially BH Air and Bulgarian Air Charter might be in a very good position. They already started changing of their fleets from russian to western airliners and german passengers will approve this (Tupolev has unfortunatly a very bad image). And Bulgaria itself is a very good adress (not only for the germans) to spend some nice and cheap holidays. so I think the "boom" will go on the next few years. But personally I really doubt that a 12 year old MD 83 will be much better/safer than a 6year old Tupolev.
Slice, maybe you are right and a few of the bulgarian charter airlines have to go togehter to one or two big bulgarian charter airline(s) to survive. we will see...
