I flew AF63 in February - please note Terminal B is split into multiple piers, each with its own individual security. My pier had access to the SAS lounge, which was terrible. Sounds like BA is better but it's luck of the draw where your gate will be so nothing reliable. Also, you have to re-clear security, even within Terminal B itself if you want to go to another pier. Generally a very poor ground experience at EWR. Not to say JFK terminal 1 is much better...but at least AF has their own (decent) lounge there

Other than that though, the flight was extremely good. New A350, seats are beautiful and have top of the line tech, and most important the bulkhead seats are insane and have a crazy amount of room. Food, generally was also really good on my flight (restaurant quality prime rib). Lobster appetizer was a bit suspicious though...
