The infinitive *valider* cannot follow the subject directly; you need the conjugated form *valide*.
Comment je valides mon billet ?
With the pronoun *je*, the verb does not take an -s ending in the present tense.
Comment je valide ma billet ?
If the ticket is feminine (e.g., *la carte*), you would use *ma*; but *billet* is masculine, so *mon* is correct.

Cultural Tip
In France, most public transport tickets must be validated *before* boarding. Metro and train stations have small orange or green machines where you insert the ticket; the machine stamps a date and time. Forgetting to validate can result in a fine if a ticket inspector checks your ticket. In some cities (e.g., Paris), you can also use contactless cards or mobile apps, but the phrase remains useful for paper tickets.
