So I called Emirates to ask what it would cost to upgrade my flight, ended up on hold for over an hour and finally got disconnected.

When I checked my booking online, it shows that I am confirmed in Business Class, able to select seats but the E-ticket receipt still shows Economy.. Mind you, I haven't paid anything yet.

Now, I plan on calling them back when I have a free 2 hours.. But just out of curiosity, what would happen if I just leave my reservation like it is? Would I be able to check-in?
