Personalised Special Diets Onboard: The Rise of Hyper-Customised Meal Options

By Julianne Ponan MBE, Special Diets Ambassador, World Travel Catering & Onboard Services Expo (WTCE)

For decades, special meals onboard were treated as a compliance exercise: a box to tick rather than an opportunity to delight. As someone who lives with life-threatening food allergies and works closely with airlines, caterers, and manufacturers globally, I have experienced this first-hand both as a passenger at risk of anaphylaxis and as an industry partner. Today, that mindset is no longer sufficient.

Passenger expectations are changing, and so is the definition of good service. Special diets –whether allergen-free, medical, religious, ethical, or lifestyle-based – are no longer niche. They are mainstream, and they represent one of the most powerful, yet under-leveraged tools airlines have to enhance customer experience, build loyalty, and differentiate in a highly competitive market.

One persistent myth in aviation catering is that special meals serve only a small minority. Dietary needs now touch every cabin and demographic. Globally, food allergies affect around one in ten adults, while lactose intolerance impacts up to 65% of the population. Add medical diets, religious requirements, ethical choices, and culturally specific preferences, and “special meals” represent a significant share of passengers onboard.

In the UK alone, 42% of households now cater for at least one special diet, with nearly one in three reducing meat consumption. These trends reflect a broader global shift. According to IATA, over 20% of passengers request special meals, while industry data shows special meal orders have risen sharply since 2021, with vegan options growing particularly fast. Yet too often these passengers still face limited choice, inconsistent quality, poor communication, and anxiety rather than anticipation. For those with allergies or medical needs, this can be stressful and, at times, dangerous.

Customer experience for these passengers begins with trust. When a special meal is handled well, it creates an outsized emotional impact: passengers feel seen, safe, and valued. When it is mishandled or unavailable, trust erodes instantly. Hyper-customisation is not about complexity; it is about precision, clarity, and confidence.

This shift mirrors wider consumer expectations around personalised health and wellness. Today’s travellers are accustomed to tailored experiences, from fitness apps to personalised nutrition. Food is no longer viewed simply as fuel, but as central to wellbeing – especially during travel, where fatigue and stress are heightened. Airlines that embrace this evolution signal innovation and attentiveness; those that do not risk appearing outdated.

Crucially, hyper-customisation can be delivered at scale through smart menu architecture. Allergen-controlled base dishes, modular components, and universally inclusive snacks allow one core meal to flex across multiple dietary profiles. This approach improves inclusivity, reduces waste, simplifies service, and enhances safety without escalating costs.

Technology is the key enabler. Pre-ordering, app-based customisation, and QR-code transparency empower passengers while improving catering accuracy and crew efficiency. These tools already exist and are increasingly expected.

Special diets are no longer a trend. They are a permanent feature of modern travel. Airlines that lead now – by listening to passengers and investing in inclusive, intelligent solutions – will set the standard for the next generation of onboard experience and earn long-term loyalty in return.
