Hello, I’m thinking of booking a business class return to Nashville from London (Gatwick or Heathrow - don’t mind). It will be a once in a life time experience sort of trip. I’m excited about all of it - spending time in lounges before the flight too

I was thinking of booking British Airways since whilst I barely have any Avios, I would like to collect some. And also, I have a little discount from a former staff member. However, I’ve seen some posts suggesting BA’s business class is something to be desired these days. Is that true? Is BA Club World still good? Or if not, are their airlines flying they route that others would highly recommend for business class experience?

Thanks.
