While Swiss has met ECARF's two-page criteria for airlines, "we are not an allergy-free airline, but allergy-friendly," said Sarah Klatt-Walsh, director of in-flight products and services for Swiss International Air Lines.
The distinction is important.
The airline has removed fresh flowers from the cabins and, starting May 1, all Swiss flights will offer lactose- and gluten-free food and beverage alternatives, a choice of pillows stuffed with synthetic materials as an alternative to down-filled versions, and unscented soaps in the lavatories.
And while the airline does not serve peanuts, it cannot claim to be peanut-free because some food items might be prepared using peanut oil. However, "pets are not a problem on board as we have a special air filter that pulls particles and animal hair downwards and out of the cabin," said Klatt-Walsh.
