You’ve seen the deals.
A plane ticket for less than the price of a pizza. €29 to Paris? €15 to Barcelona?!
How do these budget airlines do it?
Are the pilots flying without being paid? Are the planes made of plastic?
Not quite. But it’s one of the smartest business models in the sky — and today, we’re unpacking how it works.
Let’s board this topic and buckle up 🛫
A budget airline (also called a low-cost carrier) is a no-frills airline that keeps ticket prices super low by cutting out anything extra.
You pay for the seat — and that’s it.
Want to pick where you sit?
That’s extra.
Want to check a bag?
Extra.
Want water or a snack?
Yep… still extra.
But here’s the twist: this model actually makes a ton of sense for travelers who just want to get from A to B as cheaply as possible.
It’s all about cutting costs + increasing efficiency. Here’s how:
Budget airlines often fly in and out of secondary airports. These are smaller and charge lower fees to land and take off.
Flying into “London Stansted” instead of “London Heathrow” saves a lot of money.
Every minute a plane sits on the ground, it costs money.
So budget airlines get their planes in and out fast — sometimes in 20–30 minutes. That means more flights per day = more tickets sold.
Want to sit in row 12 with your friend? That’ll cost you.
Want to check luggage? Pay up.
By only including the seat, they keep base prices low and make money on everything else.
This is called ancillary revenue — and it’s a huge part of their business.
Most budget airlines use just one type of airplane, like the Airbus A320.
Why?
Because it’s cheaper to train pilots and mechanics, and buying spare parts is easier when you only need one kind.
Low-cost carriers often:
Use thinner, lighter seats (more rows = more passengers per flight)
Have fewer staff per flight
Skip fancy extras like inflight screens or Wi-Fi
Let’s say your ticket costs €20. That barely covers fuel and airport fees. So where does the profit come from?
Baggage fees
Seat selection
Food & drink
Priority boarding
Last-minute changes
Advertising and in-flight sales
All those “extras” add up — and that’s the point.
The base ticket gets you in the door. The extras bring in the profit.
Nope! They’re just extremely clear about what you’re paying for (and what you’re not).
If you travel light, book early, and skip the extras — it can be a super affordable way to explore the world.
But if you add luggage, meals, and comfort options...
You might end up paying as much as a normal airline.
Budget airlines work because they understand what customers really need (just a seat!).
Simplicity can be a superpower — fewer options means lower costs.
And sometimes, what seems “too good to be true” just has a very smart business model behind it.
So the next time you're zipping across Europe for less than the price of lunch, remember — that cheap flight is flying high on clever strategy.
