Hi

Does EK do paid upgrades at check in, like British Airways (and others) do?

I know it's not an exact science, and factors such as how full the plane is can affect things, but does anyone know how much in general a one-way paid upgrade from economy to business tends to be, in Pounds, from Heathrow to Dubai?

I'm flying tomorrow morning - certainly going by the seat map at check in, economy seemed pretty busy.

Thanks in advance for your help.
