AWould love to do a groom's cake for my son's wedding, but I have to fly. Has anyone ever done this? Any advice ? Thanks, Patty

AYes. It was my carryon. The box fit under the seat.

Many times.  I put the cake in a box, on a non slip mat, and put it in the overhead locker.

ASecurity reserves the right to open and inspect, but my boxes weren't opened. Just be sure they can be opened and resealed.

I took two boxes, measured to fit in the overhead, and they were fine.

y'know i just nestle it into the straw on the end of the broom -- sling my leg over the handle like usual -- works for me

AOf course you're all right [@]-K8memphis[/@], your black cat perfectly balances the weight of the cake on the back of the broom!

we travel incognito -- he's orange -- bwoowahahahaha

I didn't think you could take unsealed food through anymore. Like it had to be in a sealed plastic wrapper... M&Ms were ok, but not a sandwich from Subway kind of thing.

I took four tiers in two boxes in May.

And I have taken Subway sandwiches...lol...really. Worse that ever happened was I was told to bit it (show it was edible food). You ARE allowed to carry a meal on board. 

TSA notes here:      http://www.tsa.gov/traveler-information/traveling-food-or-gifts

BTW: I am sure the airport location affects things. I fly from Austin, TX

I would hate to have TSA ask me to eat a piece of a customer's cake!

Thanks for the updated info... proof that I need to get out and travel more!

remember cupcakegate?

I often travel with a completed cake.  I've also traveled with wrapped layers [as carry on] and all of my icing and tools as luggage.

On a trip this past week, though, I noticed that the new overhead bins on Southwest do not remain flat when closed :o(  so I'll only be able to make things that will go under the seat................
