Swiss Airlines are currently offering Business Class returns from London to Geneva at Economy Class prices. That puts flights from Heathrow at £123 return, and London City from £131 return in Business Class.
You need to book by 12 June, and travel by 30 September 2015. The booking needs to be made as a Business Class booking, rather than Economy Class, and the discount will be applied automatically – there is no need for a discount code or similar.
As well as lounge access, on-board champagne and more space, you will also be permitted two pieces of checked baggage (2 x 32kg) and two pieces of carry-on baggage.
If you’re after huge savings on UK to Switzerland flights, it’s also worth mentioning that Ryanair is also currently offering return flights from London Stansted to Basel from just £10.92 all-in:
Suffice to say the Swiss option is likely to be a touch more luxurious. Where you think the real value lies is of course a matter of preference…
