This link should anger you, because it proves just how many people in other countries get to fly with free booze.  A blogger put together the VERY eye-opening 'Ultimate List of Airlines That Serve Free Alcohol.'

A few U.S. carriers actually DO occasionally serve free booze.  American serves beer and wine on some flights to Europe and South America.  Delta serves beer and wine on flights over six hours.  And Alaska serves on all international flights.

JetBlue, United, Southwest, Spirit, and U.S. Airways NEVER serve free booze.
