Subject to securing seats at 00:00 on T-355, am planning a return to KUL next Spring using our Amex CV.
Was looking through current availability on LHR-KUL one lunchtime last week to confirm the Avios and Taxes/Fees charges i'll be incurring and noticed, to my surprise, that one day the following week had a pair of 1st Seats available from KUL to LHR!
Tried looking for them again a couple of min later, but they had been snapped up already!
Point being, things do pop up at short notice, even 1st - and this week seems many seats available daily in J (LHR > KUL)..
But zilch coming back...!!
