it will only happen if your using the domain in 'bad faith'
example:
apple.??
never use this domain to sell or even have adverts that reference apple products.
that is bad faith.
applereviews.??
this can be used safely as its obvious that it provides information and harder for apple to fight
this is fair use.
if your making a big sale?, hire a lawyer.
flights, tickets etc are just the sweetener to get a good deal....its common practice.
always remember.
ITS BUSINESS and its your job to get the best price, their job to get the best price.
