The carry on regulations are not airline specific. All the liquid/gel baggy thing and the # of carry-ons is regulated by TSA and taken care of at the security check point, way before you ever get to a specific airline gate.
I just flew home from Portland last night. In addition to the 1 piece of luggage and 1 personal item that is allowed on board, there were a lot of people with the quart size bags, the inspector at the "liquids" check in actually had bags if needed. Each passenger was only allowed 1 qt. bag per person. People had these bags full of travel size items. I noticed many unmarked small plastic bottles so I am not sure about "original" packaging. Upon clearance from the ge/liquid check point the qt. size bags with the allowed items were being placed back into their carryon bags.
Personally I had 1 lipstick that I did not need to declare. I checked everything else, it did make wandering around the airport when my flight was delayed much simpler.
I also brought back a case of bottled beer. The only specification was that it needed to be boxed and packaged well. I checked it along with my luggage, TSA did open and inspect it, then placed their stickers on the box and it made it home in one piece - yippy, there be some good beer drinking going on tonight.
