No. Problem is uncomfortability. Try to fly in Yak-42 and you will see (don't used other Russian airplanes, but flied 6 times with Yak-42 and I hate when I am seeing it near gates). Lithuanian Airlines allways claiming, that they uses only Boeings and SAABs, but actually, it isn't. If they are writing, that flight will be operated with 737, that means that it will be operated with 737 (50%) or Yak-42 (also fifty). In four my flights with Yak-42, was written, that they are operated with 737. LAL Magazines writes that their sold Yaks at 1996. And these magazines also are on these Yaks...
LAL has 2 B732 (also do not match sound standarts), 3 (5?) Yak-42, and 4 SAABs (2 340B, 2 -- 2000) leased. Also, leased B733. If you live in Paris and will be planning trip to Vilnius, don't use LAL -- I flew two times this route (operating plane here is "B737", it is written on tickets and in magazines), and both times got Yak... It seems that they allways uses Yak for this route. The same about routes in Antalya, Limmasol, Barcelona (all available only on summer). Why I am saying Yak-42 is so bad?
1.There is no place for foot.
2.If seat is near emergency exit, there is no desk.
3.Allways shakes, no matter, is it turbulance or not.
4.You must get to it throw backstairs, so must ride via bus.
5.There is no bussines class (all things are the same except food), so if you have a ticket to this class, you have a ticket to lottery -- will you get bussines (like on 737) or not.
6.Seats are bad, it seems that they are unchanged since the airplane was in factory.
7.Desks are small, all food with drinks doesnt places here at one time because of lack of space.
