first airline to be called "allergy-friendly."

Commonly called ECARF, the foundation awards allergy-friendly seals to foods and cosmetics.

Its advisory board uses varying criteria to evaluate hotels, restaurants and airlines.

For hotels to get the allergy-friendly stamp of approval, they must have rooms with hardwood

floors, allergy casings for mattresses and pillows as well as no allergy-containing green

plants. (Via Wikimedia Commons / Jean-Pierre Lavoie)

So what exactly is Swiss International Air Lines doing to make allergy-sufferers more

comfortable on flights?

A writer for ABC reports the airline will be offering "individualized service product."

This means, passengers can ask for lactose and gluten-free foods and drinks, including

lactose-free chocolate and coffee creamer.

"They'll also be making the switch to synthetic pillows and will stop using decorative flowers

and air fresheners to keep those with the nasal allergies breathing easily." ​(Via

In a press release, the airline explained why it wanted to be named "allergy-friendly."

"We have seen a steady increase over the past few years in our customers' need for an air

travel environment that pays due regard to any allergic conditions."

It's important to point out that being called "allergy-friendly" does not make the airline

completely allergy-free.

For example, NBC says it's not actually peanut-free because, although the airline doesn't serve

peanuts, it cannot guarantee the food it serves isn't cooked in peanut oil.

A writer for Allergy Safe Travel feels Swiss International Air Lines isn't going far enough,

especially when it comes to helping passengers with the dreaded nut allergy.

"Online, Swiss Air says they cannot guarantee a nut free flight nor can they control what

passengers bring on the aircraft. In my mind, there's still too much ambiguity to fly Swiss

Air." ​(Via Allergy Safe Travel)

Those issues aside, the airline says it will have its planned "allergy-friendly" modifications

in place by May.
