Have returned from my upgraded flights this week. Miles and TP's posted as C/I within 24 hours of flying both ways.
It's worked out very nicely for me, effectively getting me back to Silver on my next flight in a couple of weeks and putting me 540Tps to the good in requalifying for Silver or the Assualt on Gold with my next few flights. Just 20 TPs "wasted", so to speak.
