How much cash should I carry on an airplane? What amount of cash is safe to carry?

I am going to Vegas this weekend and I am planning on carrying $800-$1,000 cash in my front jeans pocket. Do you think this is too much cash to bring?|||It is not necessarily to much to carry to Vegas, but do not put it all in one place. Put smaller amounts in various places.|||Buy a MONEY BELT.. I have worn one for years and usually have at least $2000 in it, all in $100 bills because I can ALWAYS cash a small bill that size.|||well dont bring to much and putt similar ammount in different because if something does go wrong u dont want to have alll of your money in one spot.
