hey sweetie
i know exactly where you are coming from... i flew on the SAAB's for 5 years and had numerous chucks... that little white bag was always strategically placed on seat 1A when the weather was bad. i spent a few times hiding my face behind the seat and hoping the roar of the SAAB engines would drown out my loud wretching noises.. oh yeah real pretty believe you me!!
my problem was the hot summer months.. getting into a hot aircraft that had been on the tarmac on the turn around with no APU so no on ground aircon... and then taking off and being pummeled around the sky like a ride on a roll-a-coaster!!
i occasionally took travel sick tablets but found plenty of water and cold air on my face used to do the trick. i also knew a girl who first started with the company who was really sick during her training but after she was checked to line and started flying by herself no more sickness !! she put alot down to nerves... anways pet all the best and try not to worry to much!! the more you think about it the more you will chuck!!
Good luck
