Still now , 5 days later : stll present dry ache up in nose.
We fly this flight often and experienced the consequences of too dry air before. Never as bad as now.
So : my complaint is : better air quality (humidity % in cabin) please.
We know more humidity means more weight and thus fuel cost.
Bad economy.
Where will they try to save next ???

Humidity means more weight? LMAO. It's not an issue of economics
Water vapor is bad for aircraft pneumatic lines. It is conducive to ice forming at those altitudes.
Cabin air is taken from the engine compressors before fuel is added to light it off. It's very dry.
Oceanic-length flights can reduce humidity down toward single-digits.
Drink water, a lot of it. Hydrate yourself.
There is no humidity control on current commercial aircraft. The 787 is purported to have a difference pressurazation system that will increase humidty/comfort, but even now they are having some unexpected icing conditions from it.
