Jet2 launched the scheme in August 2022, during the pandemic, when its share price had dipped sharply to around £9. It offered staff shares at a discounted £7.66, with the price on 1 October this year, when the scheme matured, reaching £14.16.
Staff can now choose to sell their shares or retain them as a future investment.
Jet2 said: “Based on the 84% rise in share price over the period from the option price of £7.66, the return on the amount invested by colleagues is more than £26 million.
