Is the cheap flight really cheaper?

Not cheaper

It says $89 each. It really costs $313 each.

• It stays cheaper as long as the add-ons come to less than $159 each. They come to $204.
• For every $1 of the advertised price, you pay $3.52 in all.
• The add-ons are 72% of what you pay.
• It costs $90 in all more than the price that includes everything.

This is a worked example with illustrative figures, not data about any real person or company. Change any of them in the calculator and the answer changes with them.
