Yes, you can bring wine in your checked bag on a plane in 2026, and unlike hard liquor, there is no federal limit on the quantity of wine (under 24% ABV) for domestic U.S. travel. However, you are limited by your airline's weight restrictions (typically 50 lbs or 23 kg) and customs regulations if traveling internationally. To ensure your wine survives the journey, use "Wine Skins" or specialized bubble-wrap sleeves, and place the bottles in the center of your suitcase surrounded by "buffer" items like sweaters and thick jeans. Avoid placing bottles near the edges where they can be impacted by the baggage handling system. If traveling to the U.S. from abroad, you are generally allowed 1 liter duty-free per adult; any amount over that must be declared to Customs, and you may be required to pay a small "excise tax" (usually about $1–$2 per bottle). Note that you are strictly prohibited from drinking your own "checked" wine while onboard the aircraft.
