A man nearly got sucked out of a Ryanair window at 30,000 feet last week. His wife held his legs for five minutes while cabin pressure did its best impression of a cosmic vacuum cleaner. This is not a metaphor for the airline industry. This is the airline industry.

Ryanair’s business model is built on a simple principle: extract maximum revenue from minimum safety margins, then let physics sort out the rest. At €25 for a flight from Dublin to London, you are not paying for a seat so much as you are paying for the privilege of being in an aircraft that legally qualifies as one. The airline has turned flying into a financial game where the house always wins and occasionally the house wins so hard that a window decides to leave mid-flight.

Here is what matters to your wallet: when airlines compete on price alone, they cut costs everywhere that is not obviously fatal. That includes maintenance, redundancy, and the kind of engineering that prevents windows from becoming emergency exits. Budget carriers operate on margins so thin that a single unscheduled repair can swing a route from profitable to dead. So they gamble. They schedule turnarounds in 25 minutes. They defer maintenance. They hope nothing breaks.

For passengers, the math is brutal. Save €100 on a ticket, accept a non-zero chance of holding your spouse’s legs while the cabin depressurizes. Most of the time, nothing happens. But “most of the time” is not a financial strategy — it is Russian roulette with seat belts.

If you are choosing flights purely on price, you are not being frugal. You are being penny-wise and pound-foolish in the most literal sense possible.
