I had thought it was mainly due to drag and perhaps turbulence, but I suspect you might be referring to jet engine efficiency as well?

Could an unpressurised passenger jet ever become competitive?

I suspect the answer is no, or it would have been done already. But as technology on composite materials and advanced aerodynamics gets better all the time, could we ever reach a point when an ultralight non-pressurised passenger jet flying low becomes more efficient than the current ones despite th...

Re: Royal Jordanian forcing passengers to close window blinds on medium haul daytime flights

Those are all longish enough flights that people can take a nap and sleep. Light flooding into the cabin is a major annoyance. Easily solved by a blindfold though. Plenty of airlines provide them already on longer flights. If RJ is so concerned about passengers getting shut eye, all they need is to...

Royal Jordanian forcing passengers to close window blinds on medium haul daytime flights

Last year I flew AMM- LHR on RJ’s 787, which IIRC departs at around 11 am.
