Nice idea ..
Personally though all i want to do is to get where i am going and having someone pamper me or give me a cut throat would send me to sleep and i'd miss my flights through being too relaxed ...
aromatherapy might be an option? To give out on the aeroplanes to lift spirits and revive or pick up on the way out of the plane? Talk to the body shop and others, they might be willing to push their stuff in this way via franchises especially for flyers
