adjective

If something is up in the air, it is not decided yet. People are still thinking about it, so the final result may change.

  • Our travel plans are still up in the air.
  • The meeting date is up in the air.
  • Her job offer is up in the air.

Adinary Nuance

Up-in-the-air means uncertain or not yet decided. It is different from 'unclear', which can mean hard to understand, and from 'temporary', which means it will change later but is currently settled. Writers use 'up in the air' for plans, decisions, and outcomes that are still open.
