Basically you can walk forward a bit and perform the kick. It's basically the max height after 7K but as long as the P connects. If it's too high the P will whiff but around that distance you have to input 8K early for the P+K warp into Air T.
What I did is 66 after the PL. As soon as the P connects from the air, immediately do 8KP+K. There is a short distance from when P striked that causes her to float a bit of distance and it causes the Air T to whiff completely. It took me about 4 rough tries.
Did it just now with no repeats. 3x in 1 shot. Also my mistake. It's 8K that distances them a further back. If it waits too long, 8K will still connect into the P+K but the Air T will likely whiff.
I dunno man .. im doing it .. but ... its just not connecting ... also that whiffed P ... its pissing me off ... I got the tag one as soon as I memorized the sequence .. n this one ... im just stuck with .. lol .. guess I'll keep goin at it till it hits ..
