Flights around the holidays are already expensive. The last thing travelers need is a price increase on their alcohol.

Delta Airlines is raising the price of in-flight alcoholic beverages. Going up by one dollar, domestic beers will now be $8.00, and imports, wine, and specialty cocktails will all be $9. Delta is following the lead of American Airlines, who made headlines after raising their beverage costs in October. For customers in Main Cabin Extra seats, travelers received free alcoholic beverages to keep up with competitor Delta’s comfort + domestic drinks policy.

The turn up on flights is getting quite expensive, getting close to the same price as the drinks you can get restaurants, but more than half the size. Unites Airlines is already at the $10.00 mark after introducing a signature cocktail called the Old Fashioned. The Old Fashioned is one of the oldest cocktails out there, so there isn’t really anything signature about it. It is only free for travelers in Economy Plus seats, but for those sitting behind them, they will be charged $9.99. The price is the same for Mai Tais on flights to Hawaii.

Southwest Airlines also raised drink prices between $1.00 and $2.00. Beer and wine are now $6.00 and liquor is $7.00. On Alaska Airlines, premium wines go for $8.50. As for other drinks on Alaska Airlines, prices remain steady at $7.50 per drink. Some of the cheapest drinks you’ll find are on JetBlue, with their drinks going for $7.00. All except the tasty Ambre Selina Extra Dry Sparkling Wine, which is $9.00. Premium spirits like Bailey’s Irish Crème and Buffalo Trace bourbon on United are $8.99. Beer is set at $7.99 as well as other liquors and house wines.

It wouldn’t shock travelers if they started charging for in-flight snacks, just like what happened to a Delta passenger in August. While on a flight from Paris, a flight attendant offered her an apple and she accepted, placing it in her carry on for later. When she landed in the United States, customs noticed the unmarked apple and was forced to charge her $500.
