Here are some examples:
CATHAY PACIFIC First Class gives out: Slippers and Eyeshades in a Silver Cloth Bag. There are 2 colours(to choose from) for each amenity kit for Men and Women. The products currently used now are Declor of France. Products used in the past include La Prairie and Erno Laszlo. Kits for men would include EarPlugs, Toothbrush and toothpaste, Shaver, Shaving Cream, Facial Moisturizer, Lip Balm, Eye Gel, Face Cloth, Comb and sometimes a cologne. Products for women will be geared for women of course, so a different product range is offered without the Shaver and Shaving cream obviously and substituted with Hand/Body Cream, Brush and Facial Mist. CX
First Class lavatories offer either La Prarie or Erno Laszlo facial mists, cologne, face wash and moisturizers.
CATHAY PACIFIC Business Class gives out: Sockettes and Eyeshades enclosed in their repsective 2 colour to choose from, kits for men and women. The current product range comes from Biotherm of France. Past product offerings included L'Occident of France, and Crabtree & Evelyn. Amenities are about the same as found in First Class but obviously quality is better in First. CX
Business Class lavatories offer Evian facial mists, biotherm cologne for men, facial moisturizers.. and the usual toothbrush etc.
CATHAY PACIFIC Economy Class passengers receive sockettes and eyeshades upon request.
SINGAPORE AIRLINES only offers amenity kits for First Class passengers on flights exceeding 9 hours. Their products used are currently Bvlgari of Italy enclosed in a Givency Bag. (How unappropriate is that???)
BRITISH AIRWAYS has the nicest products for their FIRST CLASS passengers. Men get NKSpace products, and women get Dr. Haushka products. I've seen people trying to sell these First Class amenity kits on E-Bay for $250 each as they are so sought after by collectors. Men's kits are kept in a square Green Bag depicting Grass. Women's kits are kept in a Red Bag depicting Roses. The products are stored in categories: BEFORE TAKEOFF, DURING FLIGHT and AFTER FLIGHT to offer products that one should use.
Oh yes, all carriers above also give out PYJAMAS (to keep) for their First Class passengers. CATHAY PACIFIC has one of the nicest. Beige. BA
's comes in Grey, and SINGAPORE AIRLINES in Light Blue by Givency.
