The Middle East war is already making a massive impact on British lives, with prices of jet fuel skyrocketing and leading to fears of cancelled flights.
Around 40 per cent of Europe's jet fuel is sourced through the Strait of Hormuz, which is almost entirely sealed off.
UK supplies come both directly from the Middle East, as well as subsidiary routes through Belgium and the Netherlands.
The last documented shipment of jet fuel to Britain from the Middle East is expected soon, leaving a question-mark over future supplies.
In an interview with The Daily Mail, ex-airline captain Emma Henderson MBE said the situation could cause chaos in the air travel industry.
She said: "The bottom line is that if oil is not released from the Straits of Hormuz, there will come a point when there is not enough - and this is already happening in Europe where some airports have run out of jet fuel.
"I don't think people need to panic about their summer holidays being cancelled but I think we all need to be aware of what's going on and the impact it is potentially going to have on our lives.
"'It will also impact the cost of flights in the long run but not necessarily yet because large airlines hedge fuel prices and will be protected on price for most of 2026 but that's only good if you can actually get the stuff into the country in the first place isn't it."
Ms Henderson added holidaymakers could consider other methods of travel, potentially by sea or by land, and think of it as "a possible adventure". She also said "fuel hungry" long-haul flights are likely to be hit first by shortages.
The UK does not depend solely on the Strait of Hormuz for fuel, and other shipments are possible from the Middle East, as well as India, the US and the Netherlands plus smaller amounts from other countries.
This week, Ryanair chief executive Michael O'Leary warned travellers could face a year of uncertainty if the Iran War continues to hamper global trade routes.
Mr O'Leary told Sky News that Ryanair is "reasonably well-hedged" with 80 per cent of jet fuel, but disruption could affect passengers in "early May".
He added: "But if the war continues, we do run the risk of supply disruptions in Europe in May and June, and we hope the war will finish sooner than that and the risk to supply will be eliminated."
