its all got to do with how many zones and sensors options you have in your cabin, aircrafts initially meant for domestic runs,now running long range
will always have temp stabilising issues.
Also airline policy to keep cabins cold to save fuel, Air As*a X,
and then sell blankets on board.
Fokkers,
Embraers,
Bombardiers,
and Airbuses are very bad,
its also the whole aircraft bad design
badly placed outlets and louvres,
dirty airconditioning systems,
bid galleys at the back of the cabin are difficult to heat,
minimal use of insulation to save weight.
the best are the boeings,ask the people flying them.
i hope this last statement will keep the discussion going.
