>>>Unbuckling your seat belts? What about the concept of the airliner as a flying cruiseship, aka A380, with: lounges, bars, spas, pools, showers, duty free shops, bowling alleys, etc.?<<<
the same thought had occurred to me too, and I really wonder in what kind of dreamworld the adverstising managers of Airbus or their customers live...
Apart from that I have observed on several long haul trips between AMS
and Asia with KLM that at least in Business-class almost all pax remain belted.
Problem is that most pax have no access to publications like "Flight International" where you find every half year a statistic giving you what kind of incidents (fatal and non-fatal, with and without injuries) had been reported worldwide.
If any of the "unbucklers" would know how many people get hurt every year in CAT and how many planes stick their nose into the terminal-buildings or have to make an emergency-braking on the runway, they would reconsider their actions.
I think that if a passenger would be unbuckled despite seatbelt sign being on and then he hurts me because he falls on me, I would sue this person for damages!!!
