I got a free upgrade to an $11,500 seat in British Airways’ business class. It was great, but one thing could’ve made it even better.

• I booked a $720 round-trip economy ticket from Seattle to Manchester with British Airways.
• On my way back to the US, I received a surprise upgrade to business class.
• I enjoyed the business-class experience but probably wouldn’t pay full price for it.

As a Seattle-based Brit who often travels between the US and England, I love a comfortable plane ride. So, when I was upgraded to business class on a British Airways flight this past summer, I was absolutely delighted.

I paid about $720 for a round-trip economy ticket from Seattle to Manchester, and on the way back to the US, I had a layover in London.

When I scanned my boarding pass to get on the plane, the gate agent printed a new ticket and said I was upgraded to British Airways’ Club World, the airline’s long-haul business-class cabin.

British Airways, which has seen a decrease in popularity in recent years, is spending $9 billion over the next two years to upgrade its planes, customer perks, and other aspects of its business model. So, I was excited to see what the experience would be like.

Here’s what my 10-hour flight in British Airways’ business class was like.
