So some thoughts comparing bulkhead seats 2A, 2L, 10A and 9L on the A350.Travelling now on LWE to SIN in seat 9L,mini-cabin. No doubt it's very private and comfortable, and has the widest footwell of all of the bulkhead seats. I'm 195cm and found it superb for sleeping either on my right hand side, or on my back. Also seems the seat has a slightly wider entry point, so a bit easier to get in or out.However be aware, there is significant noise from the galley which may disturb light sleepers on overnight flights. Also, the crew on my flight kept the dividing curtain between the cabin and gallery open until i kindly requested it to be closed. I've now traveled on all the window bulkhead seats and can't honestly say there's a significant difference between them. They all have significant extra legroom when compared to standard seats. In the front cabin you do risk a baby as there is a bassinet connection in row 1.My go to seat till now has been 2L but maybe now it will be 9L, but only if I can be sure of no last minute equipment swap.Hope it's helpful 🙏🏼
