My flight on LH A350-900 for next summer was switched to a 1-2-1 configuration that I didn't realize they used in my route. I haven't seen it before. We are 2 people and all the seats are open in the 8 business class rows. Any suggestions for which seats to switch to? We don't necessarily need window access but we were in 4A and 4C (The two window-ish seats before on the 2-2-2 config)
