Yes. In Jainism, traveling by plane or car for pleasure is permissible as long as your intention and conduct follow ahimsa (non-violence) and other ethical ideals.

Key points to keep in mind:

• Non-violence always: Avoid harming living beings during travel (e.g., insects, animals) as far as possible. Be mindful of the routes, packing, and stopping points that minimize harm.
• Right intention: Travel for sane, truthful, non-greedy enjoyment, not for reckless indulgence or causing needless suffering to others.
• Moderation and restraint: Don’t let travel become extreme or wasteful; practice aparigraha (non-attachment) and simplicity in your plans.
• Mindfulness and ethics: Be honest, patient, and considerate with fellow travelers and service staff; avoid deceit or exploitation in arrangements.

Traditions (Digambar and Shwetambar) emphasize the same core principle of non-violence; there isn’t a distinct, prohibitive rule against plane or car travel in either tradition when it is approached with right conduct.

If you’d like, I can share a brief, traditional formulation (arth) related to travel and non-violence, or point you to a Jain Knowledge page for deeper guidance.
