So this just in from AARP, several days too late for me. http://www.aarp.org/travel/transportation/holiday_flying_tips.html

Angry, frustrated and in tears my yummy yoghurt was snatched from my bag, as I was glowered at by first the crew at Security, and then a 6 foot, 3 inch enforcer. Never have I left the Pittsburgh Airport without losing a leaf from my carry-on. This went too far.

No proper food on board for the first time in all my 40-odd years of traveling I brought some snacks. I had been so encouraged by seeing my daughter carry her lunch to work, it seemed like the right and proper gesture to carry my own food from Pittsburgh, through Chicago, to Albuquerque. No such luck! Foiled again!
