Celebrities and members of the Royal Family have made a wide range of unusual and extravagant demands while traveling by air, from ensuring complete privacy to specific culinary preferences and even in-flight fitness routines.
Pop icon Mariah Carey has reportedly booked out entire first-class cabins for privacy, once paying $118,000 for an empty cabin on a British Airways flight. Carey is also known for her demands upon landing, including a reported request for a red carpet lined with candles at a London hotel in 2005.
Singer Madonna has also made notable requests. In 2010, she reportedly practiced yoga in the aisles of a delayed flight from New York to London Heathrow, which frustrated other passengers. More recently, she has traveled with her own private chef to prepare sushi on board, adhering to a strict diet that avoids processed foods.
Television personality Amanda Holden's travel habits have been highlighted, with comedian Alan Carr noting her disappointment with budget airline Ryanair for not providing ice for her rosé wine. Carr humorously suggested that Holden seemed to expect the service of a high-end restaurant like The Ivy while flying.
Actress Megan Fox employs a unique strategy to cope with nervousness during flights: she listens to old-school Britney Spears music, stating it's "not the soundtrack to my death."
Members of the Royal Family also have specific in-flight preferences. Queen Elizabeth II reportedly enjoyed a martini before flights and always requested a bowl of Velamints, a sugar-free mint, to be placed beside her and in her dressing room. She also favored Malvern water. Flight attendants were instructed to coordinate with her dresser to ensure her bed was properly made, and she brought her own pillows.
King Charles III has demonstrated a commitment to environmental sustainability in his travel, requesting that standard jet fuel be replaced with sustainable aviation fuel on official government and charter flights. His approach has been praised as leading by example.
Queen Camilla, who dislikes flying and turbulence, has occasionally had her itineraries adjusted. For instance, she returned ahead of schedule from a royal tour of Australia in 2018 due to her discomfort with flying.
The Prince and Princess of Wales reportedly utilize the exclusive Windsor Suite at Heathrow Airport, which offers private lounges, a personal butler, and menus from Michelin-starred chefs. This suite is also used by other members of the Royal Family and high-profile individuals.
Princess Anne is said to have a fondness for Fray Bentos tinned meat pies, along with tinned vegetables and potatoes, which were prepared with a homemade gravy by the flight crew. This was described as a pleasant change from more conventional first-class dining.
Other anonymous celebrity requests have included filling an entire plane with white Casablanca lilies, demanding complete darkness by covering all windows, chartering a private jet solely to retrieve a mobile phone, and bringing food tasters to sample meals before consumption.
