WELL this is a first. Passengers on a flight in the United States drank the plane completely out of alcohol and the pilot was so impressed he congratulated them over the speaker.

The Southwest Airlines flight from California to Kansas City was only in the air for three and a half hours but that was long enough for it to be wiped out of alcohol.

Most of the passengers on the plane were American football fans travelling to support their team the Oakland Raiders who were playing against the Kansas City Chiefs.

A sports journalist, Jimmy Durkin, was on-board and tweeted about the pilot announcement.

Announcement on flight to Kansas City congratulates the entire aircraft for wiping them completely out of booze. Yep, it's a Raiders flight. — Jimmy Durkin (@Jimmy_Durkin) December 7, 2016

Despite the rise in incidents of passengers misbehaving on flights, Durkin told Fox News that the passengers on-board were “not particularly rowdy” and were just enjoying themselves.

So should you drink alcohol on a flight? While it’s not the end of the world to have a glass of wine with your meal, studies have shown that drinking at high altitude impacts the body more quickly than at ground level.

Because of the lower level of oxygen in your bloody, you may seem more drunk in the air. And with the dry air on the plane, you can become dehydrated faster.

To combat dehydration, make sure you drink a glass of water with every alcoholic beverage and minimise your intake of salty food that may encourage you to drink faster.
