Hi,
Also 62K is just ahead of the right hand side emergency exit door ( and as you face backwards you are just ahead of it which gives you the extra space.)
An extra bonus is that you are facing the cabin crew seats so you may be able to have a brief chat with them on take off and approach and landing. (62A does not have this bonus)

Flying from LHR you will have Galleries Club access ( both North and South and T5B) and you may be able to book a Elemis Spa treatment ( LHR and JFK)
