I have always enjoyed great experiences flying with Air France. Superior food and wine selection. Fantastic crew. Beautiful and well-catered lounges at CDG. As a solo traveler, the A350, B789, and B777 offer nice seats in business.
I haven’t yet flown the new business class seats launched last year but I look forward to trying those.
I also fly DL regularly and I enjoy myself too. Though I must admit that SkyClubs and catering on board are not as refined. However, I have noticed that AF catering is consistently better when departing from CDG than from the US.
As someone who grew up in a working class family, I am just grateful all around to be able to afford flying business class—no matter the airline. It’s always a treat, no matter how many times I’ve done it. 😋
