My family will be travelling to Spain next year in first class for a special occasion, and I wanted to ask whether BA first class is worth the money, or if we should go with another airline for a better first class experience (For example, I've heard some say that Air France first class experience is much better than BA first class).

I haven't flown BA for about 3-4 years, and it sounds like Heathrow T5 has unfortunately gotten even more crowded and inefficient, so despite having been a BA fan for a long time, I'm thinking I may need to make a switch...

Any thoughts?
