No, you cannot propagate air plants from leaves like you can with succulents or other houseplants. Air plants lack the right type of cells in their leaves to grow new roots or shoots. Your only options for making more Tillandsia are waiting for pups or growing from seed.
I tried this myself when I first started collecting air plants after years of growing succulents. A leaf fell off one of my Ionanthas and I stuck it in some moss hoping it would root. Nothing happened for months. The leaf just dried up and crumbled away. That failure taught me to research before trying new methods.
Air plant leaf propagation fails because these plants lack meristematic tissue in their leaves. This special tissue lets succulents grow whole plants from leaf cuttings. Tillandsia plants put all their reproductive energy into pups and seeds instead. They cannot make new plants from leaves.
A Tillandsia leaf cutting will never produce roots or new growth no matter how long you wait. The cells in the leaf cannot divide into new plant structures. Even if you keep the leaf moist and give it perfect light, it will just rot or dry out. Save your time and skip this method.
Marie Selby Botanical Gardens notes that some species do not produce pups at all. One example is Tillandsia utriculata which relies on seeds alone for new plants. This shows how air plants moved away from leaf propagation long ago. They use pups or seeds but never leaves to grow more.
Your best air plant reproduction methods start with pups from blooming plants. Most species produce one to eight pups after they flower. Wait for these pups to reach one-third the size of the mother before you separate them. This gives you the fastest and most reliable way to grow your collection.
Seeds offer another option but require huge patience from you. Air plant seeds take eight or more years to grow into mature plants. The seeds need specific conditions to sprout and the tiny seedlings are fragile for years. Most home growers stick with pups for good reason.
Focus your energy on keeping your current plants healthy so they bloom and produce pups. Good light, regular water, and monthly fertilizer give you the best odds of seeing new growth. The wait for pups feels long but pays off better than any failed leaf experiment ever could for you.
