Tips for Flying Air Sunshine

• Confirm baggage allowances and size/weight limits before booking, as regional carriers often have stricter or per-piece policies than major airlines.
• Arrive at smaller airports early because check-in and boarding can be slower and counters may open later than at large hubs.
• If you have connections with larger carriers, allow extra time - interlining and through-check of bags may be limited.
• Bring snacks and any essentials for short flights; onboard catering and amenities are typically minimal on short regional services.
