Business Class
Always confirm aircraft type before booking — the A350-900 business class is a completely different (and far superior) product to the older A330-200 configuration still flying many Latin America routes. Madrid–Barajas Terminal 4 is the best place to experience Iberia's ground product, including its flagship business/VIP lounge with a la carte dining and a cava bar. If connecting onward on another oneworld carrier, check which lounge you're routed to, as satellite terminals can mean a downgraded lounge experience outside T4.
Business Class
The single most important factor when booking Air France Business is aircraft type: the reverse-herringbone seat on refreshed 777s, 787s, and A350s is excellent, but some older A330s still fly with a dated angled or less private business product — always check the specific aircraft registration via ExpertFlyer or Seat Guru before booking. For the best overall experience, prioritize A350 or 787 routes out of Paris CDG, and note that La Première (Air France's first class), not Business, is where the truly standout ground and culinary experience lives.
