Re: plane ride..
behnjee as long as the containers individually weigh 3oz or less you should be okay carrying them in your handbag, just make sure you have them in a transparent bag/ziplock and when you pass your bags on the conveyor belt place that transparent bag seperatly on the belt, out of your bag. They have transparent ziplocks at the airports too available in the area where you get in line for the security checks if you forget.
