Welcome Gino0810. The first question to be asked, was this booked through a travel agent or directly with EK.? If EK then you can deal with them directly and ask how much you would need to pay to change the ticket to Business. In this instance you wouldn’t be upgrading but up-faring. Not sure if possible on promotion tickets but would be slightly surprised if you couldn’t. It would basically boil down to the fare difference being paid.

If the ticket has has been purchased through a travel agent, then you will have to deal with them to make any changes. EK generally waives the fare change fee to up-fare whereas you may find travel agents don’t.

Let us us know how you get on.
