If you don't get the ticket, what will you do?

The first conditional sentences (type 1) refer to the present or future. They are used to speculate about possible situations that can really happen.
We use the present tense in the if clause and will + bare infinitive in the main clause.

Other forms

Apart from the basic form (if + the present simple + will), we can use other verb forms in the first sentences.
If you have finished your dinner, you can ask for the bill.
If you are feeling tired, take a rest.
If he is a good skier, he might make it.
If you want to be slim, you should eat less.
If you meet her, can you let me know?

Note

If is the most frequent expression in the if clauses, but other expressions are also possible: even if, provided (that), unless, on condition (that), in case.
You will leave tonight even if you don't want to.
You can have your birthday party provided that you aren't noisy.
