Vanessa teaches the idiom “up in the air” for plans or decisions that are not settled yet. If a trip, schedule, career choice, or personal plan is up in the air, the details remain uncertain. The expression does not mean that something is physically floating above you. It describes a figurative state of uncertainty or lack of a final decision.
“My plans are up in the air” means I do not yet know exactly what I will do. “The trip is up in the air” suggests that it may happen, change, or be cancelled because important details are unresolved. Adding “still” emphasizes that the uncertainty continues: “My career plan is still up in the air.” “Have no idea” is a common phrase meaning that you do not know the answer or what will happen. “By the end of the lesson” identifies a deadline or point in time when something is expected to be achieved.
The idiom can describe many kinds of plans, but it is most natural when a decision or arrangement has not been finalized. You could say, “Our weekend plans are up in the air because we’re waiting for the weather forecast.” You would not normally use it for a plan that is definite and fully arranged. The phrase is conversational and useful in everyday speech.
When listening, notice what remains undecided: the date, location, people involved, or whether the plan will happen at all. Adding a reason makes the sentence clearer. For example, “The move is up in the air until I hear back from the new company.” The expression communicates uncertainty without requiring a long explanation.
For practice, choose a real or imagined plan that is undecided. Say what is up in the air and why. Then contrast it with a settled plan: “The picnic is up in the air, but our dinner reservation is confirmed.” This helps distinguish an uncertain arrangement from one that is already fixed.
