What happens if i cancel my sq flight redeemed with miles?

Do they also refund the tax paid

While you will usually get your miles back after you pay a miles redeposit fee, do note that tickets redeemed under the spontaneous escapes promotion cannot be cancelled.

You will get the kf miles back, but do note that the expiry date for your refunded kf miles will remain as recorded and not get renew-ed.

No repercussions.

u just pay rebooking or refund fees unless ur miles are expired.​​​
