How Much Does It Cost Upgrade To British Airways’ Club World?

British Airways’ Club World is the airline’s business class for long-haul flights, while Club Europe is the business class for short-haul flights to destinations in the UK and Europe; essentially is the counterpart to US Airlines’ domestic business class. Flying Club World is expensive, with transatlantic fares routinely over $5,000. For many, premium economy (World Traveller Plus) is the happy medium between the affordability of economy and the expense of business.
