Cabin temperature complaints are a daily occurrence on commercial flights, and according to a former U.S. airline flight attendant writing for Explore, asking crew to turn up the heat is the polite request they hear constantly — and can rarely do much about.

Here's the reality: cabins are generally kept between 71 and 75 degrees Fahrenheit, and crew can only nudge the temperature a few degrees within that range. Even then, the change often barely registers for passengers. On top of that, an overly warm cabin brings its own risks — heat can contribute to nausea, dizziness and fainting, especially during boarding or while planes sit through ground delays. So the slightly chilly default isn't airlines being stingy; it's the safer, more workable setting.

The practical fix is to come prepared, regardless of the season. Stepping back onto a plane in beachwear after a week in the sun is when the cold hits hardest, and blankets are often unavailable on domestic economy flights. Socks are the single most underrated item if you're flying in sandals. A lightweight travel scarf that doubles as a shawl or mini blanket is a versatile option, and a packable puffer that folds into its own pocket stows easily in a carry-on. For winter travel, merino wool or cashmere layers make a noticeable difference. Travelling with kids? Pack layers for them too — crew simply won't have a spare blanket to hand out.

That said, don't suffer in silence. If the cabin feels genuinely too hot or too cold, or you're feeling unwell, telling a flight attendant is absolutely the right move. They can make small adjustments and keep an eye on anyone who's struggling.

Why does this matter for travellers? Because it reframes in-flight comfort as something you can mostly control yourself. Rather than banking on a crew member fixing the temperature — which they often can't — a little packing strategy delivers a far more comfortable flight. It also spares the crew a request they field dozens of times a day and can rarely resolve. Next flight, throw socks, a scarf and a foldable layer in your bag and thank yourself at cruising altitude.
