Actually, you are going by Federal liquor import regulations. It is also a Federal regulation that if state law in the port of entry is stricter than Federal law, then the state law applies.
From the TABC website:
A person traveling into Texas from another state or country can bring a maximum of:
•1 gallon of distilled spirits; (that's approx. 4 fifths of liquor)
•3 gallons of wine; and
•24 twelve-ounce containers of beer
I was not aware that the Texas law also applies to travelers from another state, but the allowances are more liberal than they used to be. The website also mentions that Texas taxes must be paid on any alcoholic beverages brought in. However, as Mikey said, you will clear Customs in Puerto Rico; so, unless you get off the plane in Dallas and blab the contents of your luggage to a Customs or TABC officer, you should have no problems. In fact, you probably won't even arrive at Terminal D where all the Customs officers are located.
P.S. I hope you don't gamble away all your money in the ship's casino. If you are going to bring back 1 gallon of liquor, a case of beer, AND 3 gallons of wine, you are going to have a huge excess luggage bill to pay at the airport in San Juan. 🙄
I've never understood the attraction of importing booze when flying. Not only is it liquid (which is heavy) but it's almost always packaged in glass (heavy and potentially breakable). I'm not a non-drinker or opposed to alcohol - I just don't get the appeal of carrying slightly cheaper booze over long distances. Costco frequently beats duty free prices and lately, even Kroger (Ralph's here in California) has been offering an additional 30% off if you buy any six bottles of alcohol, mix and match. In that sale, Bailey's was $10.99/750ml, as cheap as I see it in the DUB airport. Absolut was the same price for any flavor. Cheaper than duty free. Recently bought some JW Blue at Costco for $125/750 ml.
If you live in a dry place, I guess it might save you a drive to an adjacent county, but if booze is available where you live, why bother carrying it when traveling? I like to keep my bags as light as possible.
