Passenger Comfort.....

I'm a relatively new commercial pilot and have had several passengers
with NPE...near puke events! Some have been uncomfortable from the
moment we start the tow, others at altitude and others while
thermaling. I keep the chatter going, recommend steady breathing and
to look at the horizon. I make sure the air vent is open as well.

Can anyone offer some tips to keep the passengers from losing it? I
want each one to have a great ride and first gliding experience. I
keep the manuevers gentle and frequently ask how they are doing.

It seems the ones who say they will be fine, and laugh at me when I
point out the airsick bag, have been the one's to get queasy.

Thanks in advance,

Douglas
