Worked examples / The price and the add-ons
One round-trip ticket at $89 with a bag that fits under the seat, any seat, and $18 of fees, against $268 on the other airline.

It says $89 each. It really costs $107 each.
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.
How this answer was worked out| Add-ons each | $0 + $0 + $0 + $18 = $18 |
| It really costs | 1 x ($89 + $18) + $0 = $107 |
| Each | $107 / 1 = $107 |
| Everything included | 1 x $268 = $268 |
| Room for add-ons | $268 - $89 - $0 / 1 = $179 each |
