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.
“A colleague who had invested the average £227 a month in the three-year scheme stands to make a gain of approximately £6,922 from their £8,172 investment. Colleagues investing the maximum £500 a month stand to make a gain of approximately £15,261, if they opt to sell.”
The brand has since offered staff another three ShareSave schemes, offering investments at a 20% discount, although these are unlikely to be as lucrative because the pandemic lowered the value of the company in a period when travel was banned.
Steve Heapy, Jet2 chief executive, said: “We continue to grow and succeed by focusing on a simple philosophy of 'people, service, profits' and we are delighted that our hard-working colleagues can share in the success that they helped create.
“Their passion and tireless dedication to delivering industry-leading levels of customer service is what drives our continued success, so we are incredibly pleased to see that effort rewarded through our ShareSave scheme.”
