When I checked my flight booking (already ticketed) via "Manage a Booking", I saw a link "Upgrade your flights using Skywards Miles". This sounds cool because I don't have to call up Skywards or EK to upgrade my flight. Has anyone got experience with EK online upgrades? Is it easy to get seats?

Oh yes, you needn't key in your date of birth to log into your account on Skywards.com & Emirates.com anymore ^
