I'm on LX288 ZRH-JNB in November I have the options of sitting 23A or 30K. Both are listed as having extra leg room. 30K looking like the better choice for me as it is off the wing and on the right side. I've never sat near the lav on a over night flight.
So my first question is the lav location really that bothersome?
If so is 23A that much better or are there better seats to try for?

Thanks
