The airport operates from one compact terminal where check-in, security and departures are all within easy walking distance. The terminal handles scheduled regional services and a sizable seasonal charter and leisure traffic volume; boarding often uses walk-boarding (remote stands) rather than airbridges.

The airport is a short drive from Westerland (about 10-20 minutes) and is well connected by road. On-island transport options include taxis, local buses and car hire; there is no direct rail link to the terminal (Sylt has rail connections to the mainland via the Hindenburgdamm but the station is in Westerland town).

• Bus / local transport: Local island buses connect the town and points of interest; check schedules seasonally.
• Taxi: Taxis are available and provide a quick link to Westerland and other island destinations; fares are higher than on the mainland.
• Car hire / driving: Car hire is popular for exploring the island; desks are located at or near the terminal.
• Ride-share: Ride-share services are limited on the island-use taxis or pre-booked transfers.

Facilities are geared to short-haul leisure travellers: cafés, snack bars and a small range of shops. Free Wi‑Fi is usually available in the terminal but may be limited in duration. There are car-rental desks and basic business amenities; large lounges are not typical. Accessibility assistance is available-notify the airline in advance for help on arrival/departure.
