Luggage can be a bear to carry when it is full. Lightweight luggage can be easier to manage and can often be as durable as heavier counterparts. When purchasing this luggage, ensure that the material is durable and tear proof. Padding and extra protection in the right places will help it stand up to abuse. With the right luggage, one can manage getting in and out of buses, planes and cabs that much easier.
When planning your packing strategy it really helps to have a luggage rack carriers where you can carry some gear, as a car or truck full of people leaves little space for luggage. However, you want to make sure that what you're carrying on the luggage rack is going to be safe up there. Make sure you are storing things up there in hard containers. A soft container or sheet could come loose with the wind and blow off, or become unfastened if the load moves around. Also make sure that what you have on the luggage rack is weather proof, in-case you get caught in the rain. You wouldn't want to arrive with wet luggage for example! If you must keep soft and non-weather-proof items on the luggage rack carrier then purchase a hard shell that will protect them from the wind and the elements.

Checked luggage yes.Check out liquor-luggage. Liquor-Luggage is a new company in 2009. They make travel cases for alcohol and wine.

Then I put each bottle in a 2-gallon ziploc, then put each of those in another 2-gallon ziploc, so I had two "double bags". Then I put them both in the middle of my luggage wrapped in clothes so they wouldn't hit each other in transit.Just be careful. :)
