which fare class are you travelling in for the Y sectors?
As far as I know, EK will never say "no pentalties"
its usually :
Cancel before depart: 0 AED Cancel After Depart: X AED for a fully flexible fare
As far as I know most economy sectors dont offer refunds after departure.
When I cancelled my "K" ticket, I paid around 50% of the total price to cancel the whole ticket
