SWISS is offering a special business class fare of £199 between Heathrow and Zurich. I will be flying this myself in two weeks so I will be able to report back on how it was, hopefully before the offer ends.
You need to book by 14th February for travel before 31st December 2018.
Your best option to maximise your miles when paying is American Express Preferred Rewards Gold. This offers double points – 2 per £1 – when you when you book flight tickets directly with an airline. Our review of Amex Gold is here.
If you visit this special page of the SWISS website you will see a calendar which shows at a glance which days are available at this price. Availability looks very good to be honest.
Remember that SWISS uses Terminal 2 at Heathrow and you will be able to access the Lufthansa lounge – or, if you’re willing to walk over to the satellite terminal, the fantastic United Club lounge (or the less fantastic Singapore Airlines and Air Canada lounges).
