When SFX entered service, it was more or less ok with the old interior. And yes, it was old. But after a few months, it was a nightmare, no spare parts, no spare cushions and/or covers. At the end, before it got its SN interior, it was hiddious.lumumba wrote: ↑12 Jun 2018, 17:26 I can not compare with the new one but in Y the interior of Singapore Airline (SFX) was cleaner than the Y in SN plane's....
I think that they changed the seats but not all the interior for example I was seated on 37A ( it was a 200)in my last flight and the carpet was loose on my feet it was dirty!
Normally they have to change every 5 years I tough like that?
I'm not sure the interior of SFX is older that 6 years!
Also the there is no humidity in the windows of SFX in the older SN plane's yes you can not look true the windows anymore....
As for carpets, they are replaced regularly. But the abuse is immense. Impossible to keep clean.
There is no requirement other than operators choice to replace an interior. If maintained well, it can last forever. It just won't be competitive anymore. That's the clue.
As for condensation, could be. Lots of factors play a roll in that though… But I won't argue that with age the airco distribution system looses some of its efficiency in this particular aspect.
