If you don't have a dedicated travel pillow in 2026, you can create a "DIY" version using items already in your carry-on. A bundled-up puffer jacket or an oversized scarf is a classic "hack" that provides adjustable loft and softness. For window-seat travelers, a stuffed backpack leaned against the fuselage can provide a sturdy surface. If you are in the middle or aisle, a rolled-up sweatshirt tucked into the "U" of a standard neck rest can offer better lateral support. Some "power travelers" even use an inflatable beach ball (partially deflated) for a customizable firm support that takes up zero space when empty. If your plane has adjustable headrests, "winging" the sides inward can act as a built-in pillow. In 2026, some airlines have even begun providing "ergonomic headrests" that negate the need for a separate pillow, so it's worth checking your seat features before you start "bundling" your gear.
