Genuine question to anyone here who regularly flies 777 as pax or crew: am I imagining things or is the air particularly dry on the aircraft? The longest sector on a 777 I've paxed on was DXB-DUB, roughly 8 hours and my mouth and nose were drier than Ghandi's sandals. In contrast I flew DUB-SFO on an A330 for 10.5 hours and no such problems.
Don't flame the controller btw for any Jockeys who decide to answer, we're humans too!
