Can you still select a seat or is the whole on line check in system not available?
I know from past experience using my ALT from LAX-DXB that I could select my seat on line but I could not create my own boarding pass since my credentials had to be verified at check in. That was no problem as I had a bag to drop off. EK unlike many other airlines, doesn't ask if you will be checking in bags when checking in online. There would be nothing to stop someone with hand luggage, checking in online and going direct to the gate, where only a cursory glance of you passport is often made.
