The amount of "drink" you can bring on a plane is strictly governed by the "3-1-1" liquids rule for carry-ons and weight limits for checked bags. For carry-on luggage, you are limited to containers of 3.4 ounces (100ml) or less that must all fit into a single quart-sized, clear plastic bag. This applies to water, juice, or sodas. However, there is a major loophole: once you pass through security, you can purchase as much liquid as you want at airport shops or refill a reusable bottle at a water station to bring on board. Regarding alcohol, you can pack an unlimited amount of beverages under 24% ABV (like wine) in your checked luggage, and up to 5 liters of spirits between 24% and 70% ABV (80-140 proof). It is crucial to remember that while you can bring these on the plane, it is a federal violation of FAA regulations to consume your own personal alcohol during the flight; all alcoholic beverages must be served by the airline's crew. This ensures the crew can monitor passenger sobriety and maintain a safe environment for everyone in the cabin.
