Deltaâ€™s offering is Calm, an eau dâ€™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 Canadaâ€™s low-cost rouge operation. Spainâ€™s Iberia is close to launching its own aroma, and Alaska Airlines is working on one.
The companies donâ€™t plan to bottle their scents for retail, but they do see a commercial value in them.
