But for some family issues I have to be at home before 29th april so I like to go back on 27 or 28 april.
Will it be possible to change the dates of my ticket for free and if I would have do an upgrade to bussiness on the A380 with KF miles how much points will it cost me

Thanks

You need to look at the ticket conditions for it before you change.

As for upgrading - only SYBM and E classes are eligible with KF miles. Yours is booked in W and is not eligible. In any case, since there's no saver upgrades for the A380, IIRC, it would cost you 100,000 KF miles one way to upgrade, provded you had the right booking code to begin with.

You've got a mix of W and E booking classes. If you can make the change, there would probably be a change fee on the order of $100 or so. You might also have to pay the fare difference into a higher booking class depending on how full the flights you want are.
