My empathy is with NYTA here. It's not "babysitting". It's just keeping a standard for good business practice.
Wife and I just got approved for UK Registered Traveller. They were pretty picky about our showing use of LHR 4X in the past 2 yrs, but we sent in enough stuff to get it done. Will get our final approval on our next visit to LHR in Nov. If it works like US global entry, we'll be pleased.
