You will be seated in economy class during the feeder flights to one of the Lufthansa group hubs Munich, Vienna or Zurich. Both Swiss and Austrian deploy a Boeing 777 on flights between their hubs and Bangkok, while Lufthansa operates their Airbus A380. All these routes use a 2-4-2 seating pattern in premium economy, compared to the 3-4-3 in economy class.
Search & Book
The fare rules don’t give away a sales or travel period for this deal. You have to stay less than twelve months in Thailand to get the lowest fare. Departures are available between August 2025 and April 2026.
Google Flights helps you find additional flight dates or compare prices. Booking through Lufthansa’s website makes most sense, as that’s also the cheapest place to buy them.

The local currency is the Thai baht (THB), and while credit cards are widely accepted in hotels and large stores, cash is preferred for smaller vendors. The city is relatively affordable, with street food and public transport offering great value. Bangkok has a tropical climate, with hot and humid weather year-round, a rainy season from May to October, and cooler, more comfortable temperatures from November to February.
