no hooks, just tube flies this trip, but apparently hooks and scissors shorter than 7'' are allowed. i used nail clippers in place of scissors before i found that out. the water based head cement raised an eyebrow until they saw what it was and determined it to be "harmless". ive never had a problem with lighters, even when they were placed in plain sight on those small plates with my wallet, keys, etc.
In 1999 I had an opportunity for a last minute trip to Christmas Island, which meant I had no flies. I tied on the flight from Seattle to Hawaii, and each night at Christmas Island.
I am amazed you were allowed to take that stuff with you in this day and age! I suspect you had a backup plan in case they didn't allow it on . . . what were you going to do? I travel from time to time, and I'd rather tie than read the in-flight free airline magazine.
