US airline Delta offers First Class and Delta Comfort + passengers free beer and wine on all flights over 500 miles.

The airline took customer feedback and consulted with healthcare professionals before reintroducing red and white wine, Heineken, Miller Lite and SweetWater beers on flights.

“All of our food and beverages are served in the safest way for both customers and employees,” said Allison Osband, Delta Senior Vice President of Onboard Services.

Flight attendants pass cans and disposable bottles using trays to minimize contact. Experts have found that beer and wine selection has fewer tactile points than other adult beverage options.

“We always listen to the opinions of our customers and know that beer and wine are the drinks for adults that are in the greatest demand on the flight,” the company believes.
