What Mrs 40 doesn't say, is if she drinks the first pot herself! Personally I take along mint tea bags - don't seem so temperature sensitive but being a mean b. don't offer them around too much...
BTW I remember the arguments about whetehr you should put milk in first (MIF) or tea in first (TIF) but I guess that's academic in flight.
Japanese Green tea (JGT) used to be refreshing a while back but American Black coffee (ABC) is still sometimes needed...
After all these abbreviations we had better not mention the old TWA beverage either...
