Up in the air
English Idiom
Meaning: When something is uncertain or undecided, it means the final outcome or decision hasn't been made yet. It indicates that things are still in progress and could change at any moment.
Origin: The idiom 'Up in the air' dates back to the 18th century, originating from early aviation and balloon travel. When a balloon was 'up in the air,' its destination and outcome were unpredictable, giving rise to the phrase.
