Blankets. Business and first-class flights offer comfort items like blankets during the flight. You must leave them on board when you're leaving the plane as they can be reused.

Generally, no, you are not allowed to keep airline blankets; they are considered "onboard equipment" and are collected by the crew at the end of the flight to be laundered and reused. In 2026, airlines are increasingly focused on sustainability and cost-cutting, so removing a blanket is technically considered theft. While the "fleece" blankets in Economy are often inexpensive, the high-end duvets and Missoni-branded bedding found in Business and First Class are quite valuable and are carefully inventoried. However, there is a minor exception: if the airline provides a disposable "travel kit" that includes a small, thin blanket in a sealed plastic bag (common on some long-haul budget carriers), it is often yours to keep. If the blanket is loose and part of the seat setup, leave it behind. A peer-to-peer essential for 2026 is to simply bring your own lightweight travel blanket (like a Matador or Rumpl) which ensures better hygiene and avoids any awkward "theft" conversations with flight attendants upon landing.
