The benefit of doing this is that many European airlines charge a majorly reduced price for long-haul flights if you travel via their central hub city, particularly in business class.
Swiss Air operates out of Terminal Two at Heathrow. I only discovered on this trip that Swiss Air is now owned by Lufthansa (as is Austrian Airlines and Brussels Airlines).
Passengers in Swiss Business Class can check two pieces of luggage weighing up to 32 kg per bag.
Flying with Swiss Air means passengers can use any of the lounges at Heathrow Terminal Two that are part of the Star Alliance network.
I enjoyed some delicious rare tuna with salad and some fantastic swiss cheese. The meal often comes with an apple dessert and swiss chocolate is given out.
On long-haul flights, Swiss Air flies the Airbus A330-300 and A340-300 and the Boeing B777-300ER.
