'Do they know it's Christmas?' an ensemble of preening and screeching entertainers from Britain called Band-Aid once inquired of listeners to their festive-themed, fund-raising sing-a-long.
To which I would reply, also failing to hit the high notes: "By simply checking the fluctuating prices of plane flights and noting those days when prices quadruple, they would be left in absolutely no doubt when Christmas was."
A brief airborne puddle jump during the Christmas period costs about the same as an overnight long-haul schlep at any other time of year. Flying to Baltimore from Boston in coach suddenly costs the same as flying first-class from Boston to Brisbane at any other time of year.
A two-hour plane trip should not be a red-eye flight, but it is at Christmas when your eyes become bloodshot from vigorously rubbing them in disbelief at the astronomical sum printed on your credit card receipt.
Borrowing a dubious leaf from the Bible, it would not surprise me if the airline lobbyists persuaded the government to enact a modern-day Census of Quirinius, requiring all citizens to be registered in the place of their birth by the end of December, thus entailing a mass purchase of plane tickets at hugely inflated Christmas prices, as it's difficult for a guy and his pregnant wife to get around on a donkey these days.
So, for me, it's not just a question of do "they" know it's Christmas but do "I" even know it's Christmas, it being easy to confuse Tidings of Comfort and Joy with Declarations of Personal Bankruptcy at thirty-five thousand feet in the air.
There may be no snow in Africa this year, as the song goes, but there will certainly be an avalanche of travel bills to be paid.
