Which future do you mean?
English has no single “future tense.” Instead we choose between several forms, will, be going to, the present continuous, and even the present simple, and the one we pick signals how we see the event: a snap decision, a firm plan, a prediction, or a fixed timetable.
Take the news that a 24-hour walkout is looming over Paris’s airports: some outcomes are firm plans, others are predictions, and a few are still just spontaneous reactions. Choosing the right future form is how you keep them apart.
The four forms at a glance
- will + infinitive: snap decisions, promises, and predictions you simply believe: “I think the strike will go ahead.”
- be going to + infinitive: intentions already decided, and predictions backed by evidence in front of you: “Those queues are going to get worse before midday.”
- present continuous: fixed arrangements with a set time or place: “The crew are pushing back stand 42 at 09:00.”
- present simple: timetabled events that run to a published schedule: “The first relief flight departs at 06:15.”
Watch the meaning, not just the form
The tricky pairs are will versus going to, and going to versus the present continuous. Reach for going to rather than will when a plan is already made or the evidence is visible; reach for the present continuous rather than going to when the arrangement is fixed and diarised, down to the time and the gate. That leaves will for the unplanned, the offer you make on the spot, or the prediction you cannot yet back with evidence.
Choose the right form
For each sentence, choose the option that best fits the context, then check your answers.
“Why are the handlers putting their high-vis vests on already?”, “Because they ___ the apron during the walkout to keep a few flights moving.”
An intention already decided: the preparation shows the plan is set.
Look at the departures board. It has just turned red. That queue at security ___ even longer.
A prediction based on present evidence.
According to the published timetable, the first wave of departures ___ at 06:15, strike or no strike.
A scheduled, timetabled event → present simple.
Don’t worry about your connection. I ___ you the moment the badge office reopens.
A promise made spontaneously at the moment of speaking.
The pushback is all arranged: the tug ___ the A320 off stand 42 at 09:00 sharp.
A fixed arrangement with a set time → present continuous.
Unless the unions and management reach a deal tonight, thousands of passengers ___ their flights on 18 June.
A prediction about a likely consequence.

Future forms and conditionals overlap the moment will appears: once you are confident here, see Structure: ‘First conditional’ for what happens to that will after if and unless.
