Is SWISS Wi-Fi free? Who gets it, and when

Short answer

Only for some passengers. Full Wi-Fi is free for SWISS First guests and HON Circle members. Everyone gets free messaging.

EveryoneFree messaging only
Free unlimited messaging throughout the flight. On selected aircraft, and always on short-haul, you must log in with a Travel ID or Miles & More account.
SWISS First guestsFull Wi-Fi, free
Complimentary internet access on SWISS-operated flights.
HON Circle membersFull Wi-Fi, free
Complimentary internet access on short/medium-haul when logged in with Miles & More or Travel ID.

Long-haul Premium is quoted as "from" — CHF 25/35 are floors, not fixed prices.
Continental and intercontinental vouchers are not interchangeable, and you cannot combine a short-haul and long-haul package in one purchase.
Vouchers are single use, valid for the year of purchase plus three following years.
The published package description lists audio streaming — not video streaming.

The connectivity provider.

Airlines change these terms without notice. Treat this as a strong prior, not a guarantee.
