Everyday Casual & Workplace

Up in the air

Up in the air
Uncertain, undecided, or unresolved; a situation where plans or decisions have not been finalized.
History & Origin

The idiom stems from the literal concept of tossing objects into the air, during which their final landing place or outcome remains entirely unpredictable until they ground. It gained widespread popularity in the mid-20th century, drawing a strong mental parallel to a coin toss or juggling where nothing is settled while the items remain suspended. Over time, it transitioned from describing physical objects in motion to abstract plans and schedules that lack a firm foundation.
