As of 2026, the traditional practice of airlines handing out free, sticky-back paper luggage tags at the check-in counter is still standard for checked baggage. These "bag tags" contain the barcode used by automated sorting systems to ensure your bag reaches the correct aircraft. However, for personal identification tags (the ones where you write your name and phone number), most airlines have shifted away from providing these for free. Passengers are now expected to provide their own durable, permanent tags to comply with international aviation safety recommendations. Some premium carriers and loyalty programs (like Delta Medallion or United Premier) still send personalized metal or plastic tags to their elite members. For "self-tagging" kiosks, which are the norm in 2026, the machine will print your flight routing tag, which you must attach yourself before dropping the bag on the conveyor belt.
