Doesn't look like they will change anytime soon (dated October 3rd):
If you have plans to travel in United Economy® or Economy Plus® on international trans-Pacific flights, intra-Asia flights and Micronesia flights, you’ll notice that we now offer complimentary beer, wine and sparkling wine. We also offer complimentary sake on flights between the mainland U.S. and Japan. You may purchase spirits, liqueurs and cognac wherever you fly.
Note: Our newly aligned drinks policy includes flights from Guam to and from Honolulu.
