I get nose bleeds on the 757/767 so it must be a Boeing issue! Only get it during the winter so it's related to snow and Boeings.
Well, maybe the dry air, dry house heat to dry airplane to dry hotel room, has a bit to do with it.
And Airbus' don't suffer from the same dry air/high cabin altitude because they can't fly high enough so the cabin altitude is lower vis a vis Boeing products.
