My parents are approaching their seventies. I've eventually converted them to the virtues of business class travel. I explained to them time and time again how travelling business class would benefit them since we live at opposite sides of the world, eventually I explained that if it was the case of them deciding not to travel because t was too difficult or to travel in business class less frequently than it might be possible. The last flight to the antipodes they upgraded and realised that there is a massive difference, no queues at check in, no queues at security, lounge access, much more attention onboard etc, this can make the difference for an elderly traveller.
