# Not All Logic is Logical

So, I recently heard a radio announcer on
Mix FM confidently giving advice to listeners saying that if you check in
for your flight early, you might have your bags to be one of the last to come
out on the carousel when you arrive. Conversely, if you check in for your
flight late, your bags are going to be one of the last to be loaded on the
plane and therefore the first to come out and you’re gonna get it on the
carousel early. So, the conclusion was check in late for your flight, so that
your bags are going to be one of the first to come out of the carousel and
you can leave the airport early. It’s a conclusion based on a logical assumption
it makes sense and likely, the radio announcer would have experienced it when
he checked in late and happened to have his back come out early.
But I do know a thing or two about airline operations and this actually is
not the case because there is no linear path that goes straight from the
conveyor belt at the check-in counter right to the plane. The bags that go down
that conveyor belt, do not go straight to the plane they reach a staging area, and
the bags keep coming up. And later the baggage handlers regrouped the
bags put them on the trucks that you see carrying bags and then they head off to
the plane. Because it doesn’t make sense to do multiple trips of the plane. And at
the staging area whether your bag comes first or it comes later, the order is not
necessarily followed in that sequence. Likewise, when it gets loaded on the
baggage truck with the multiple compartments, it isn’t always the case
that the first compartment gets loaded up first. Because it depends on when and
how the the baggage train approaches the aircraft. Whether they can start loading
from the front or sometimes they start loading from the back. And so, it really
is random. There isn’t a rule that says what happens at the check-in counter
will necessarily flow all the way to the arrivals point. So, this is a good
reminder for me and I hope it is for you too. What assumption are we
holding on to? The beliefs just because it sounds logical or we may have
had a few limited data points of experience, but on reflection is it
necessarily really true.
