Does US Airlines limit the size of the suitcase carried onto the plane?
The majority of airlines have restrictions on the size of both carry on and checked bags. Passengers who plan to fly on US Airways should make sure their carry on bag is no bigger then 45 inches. If you have concerns there should be a measuring device in the check in line so that you can make sure your bag is the proper size.
Airlines do not restrict the amount of liquids you carry in your suitcase - you could pack it with as much alcohol as you'd like. But - if you're visiting a foreign country, that country will have limitations on how much alcohol you can take into the country. Each country has different limits which are detailed in their customs regulations.
