They've always had it as do many other FF programmes for their top tiers. i use these all the time and here is my tally of how well they work:

BA: 20% of the time, if there is any sort of event whatsoever at the destination BA will usually use it as an excuse to not do it.
BD:90% of the time
DL: 100% of the time
LH: 100% of the time and applies to all cabins
