The fare said $39.
You paid $214.
A carry on bag. A seat assignment, because otherwise they will separate you from your child. A checked bag that cost more than the ticket. Printing a boarding pass at the airport. A bottle of water on board, which was $4.
And the strangest part is this. You were not deceived, exactly. Every one of those was disclosed. You clicked through each one voluntarily.
Now here is the thing that should make you pause.
That airline may have lost money on the $39. Genuinely. The fare might not have covered its share of the fuel.
It made its money on the fact that you brought a bag.
Which means the ticket was never the product. The ticket was the qualifying round, and the actual business begins the moment you have committed to the trip.
Everyone hates this model. Everyone also keeps choosing it, because when two flights appear side by side and one says $39, the human brain has already decided.
Let me show you how the machine works, because it is more sophisticated than it looks.
