Whether an airline charges for alcohol depends heavily on the route, the carrier, and your class of service. On most domestic flights in the U.S. and Europe, economy passengers are typically charged for beer, wine, and spirits, with prices ranging from $8 to $12 per drink. However, on long-haul international flights, many full-service carriers like Air India, Emirates, or Lufthansa provide complimentary alcoholic beverages even in economy class, though these are usually subject to crew discretion and "per-hour" limits for safety. In Business and First Class, alcohol is almost always complimentary and features premium selections. Low-cost carriers (LCCs) like Spirit or Ryanair always charge for alcohol regardless of the route. It is important to remember that you are legally prohibited from drinking your own duty-free alcohol on board; all alcohol must be served by the flight attendants to comply with aviation safety and sobriety regulations.
