Delta’s offering is Calm, an eau d’aeroport that it sprays in airplane cabins and infuses in the hot towels it gives out in premium classes. It has been spreading Calm for about two years, joining a handful of other carriers vying for olfactory distinction by developing their own individualized odors. The fragrant fliers include United Continental Holdings , Turkish Airlines and Air Canada’s low-cost rouge operation. Spain’s Iberia is close to launching its own aroma, and Alaska Airlines is working on one.
The companies don’t plan to bottle their scents for retail, but they do see a commercial value in them.
