The Nov/Dec 2010 menu adds kettle popcorn chips (which are excellent -- they ran out on my return trip this weekend) and no longer lists the plaintain chips (although they were still being handed out this weekend). Also there are two seasonal items: Linden's Butter Crunch Cookies and the frosted animal crackers. No sign of last year's seasonal special, the Terry Sweet Potato Chips.
I'm surprised this important topic isn't discussed more on here.
Sweet Potato Chips return to the Blue Chips at the end of Feb or into March, however the stock lasts. I've also noticed a return of some of the regular animal crackers and CC Cookies. In Feb we will have the Sea Salt Popcorners Chips. We can't keep the Popcorners on the aircraft. The customers LOVE them
