I'm flying from NCL on Tuesday (school holidays start this week up here). I've never felt the need to use fast track security before, but as our flight to Lhr is at the same time as the New York flight plus I expect a number of charters/LCC I was wondering about eligibility. We have a separate revenue flight connecting to avios CW/F BA flights. I have Marco Polo gold. It would be good to get through security as quickly as possible with the kids in tow!
