If you don't have it I highly recommend the Maclaren organizer. http://www.amazon.com/Maclaren-Universal-Organizer-%2d-Carbon/dp/B000FAKYRY Best 19.99 I spent. It held our ponchos, a change of clothes for DS (in a ziploc), plus another gallon ziploc with diapers and wipes. Plus we could put in a few snacks. I had several mothers stop and ask me where I got it. Another plus, with the mesh bag security can see right through so no issues with bag check.
