I have EK seats for me and my wife for a return flight from Europe to Dubai next month, I made the booking a few months ago and now my plans have changed.

At the time of booking I upgraded my seat to J using my miles.

My miles were used for upgrade before expiry but they would have expired If i hadnt used them.

I have options to either cancel or change dates for my flight,

How is the best way for me to still use the miles that I have on the upgrade?

Do I change the date and look for a seat in J?

Can I cancel and then does EK give you a reciprocal extension to re-use these miles that would have otherwise have expired?

All help and strategy would be greatly appreciated, funnily enough i purchased these flights to use my miles!
