A simple rolled towel can help support your cervical spine and reduce neck pain. Here's how. Find a small, hand-sized bath towel and fold it length-wise in half. Roll it up firmly so it has a diameter of 3 to 5 inches, and use rubber bands or duct tape to hold it tightly together.

If you find traditional U-shaped neck pillows bulky or uncomfortable, there are several effective alternatives that can help you sleep on a plane. One of the most common and versatile options is a large scarf or pashmina; by folding it into a thick rectangle and wrapping it snugly around your neck, you can create a custom support system that prevents your head from nodding forward. Another great trick is to use a thick hooded sweatshirt. If you wear the hoodie and stuff a soft item (like a rolled-up t-shirt) into the hood on one side, you can lean against the window or the seat wing with cushioned support. Some travelers prefer using a rolled-up jacket or blanket secured with a hair tie or small strap to create a firm "bolster" for the neck. If you have an aisle seat, a small inflatable beach ball (blown up only halfway) can be placed on the tray table in front of you, allowing you to lean forward and sleep "massage-table style." Lastly, simply utilizing the adjustable wings on most modern airplane headrests can often provide enough lateral stability to keep your head in place without needing an extra accessory at all.
