Hi,

Once OLCI opens it depends on the flight itself, if its busy then sometimes EK will auto allocate seats, other times its open for you to select any preferred seat except for extra leg room seats. The same applies if you book a saver, its only Flex fare which includes preferred seat selection after booking. Sometimes its useful to see the seat map just before OLCI opens, I have had it where you cant see the seat map at all, and the call centre staff can, so having an idea where I want to go helps
