Hi ladies, we're flying with Ryanair to Gran Canaria on Friday but we're only taking hand luggage (it's a girls only weekend!). I understand that we can only take one piece of luggage on board weighing 10kg, but what if we buy stuff after checking in but before boarding, say books in WHSmith, or a sandwich, bottle of water etc? Are we not allowed to take these on in a seperate carrier bag or do they all have to fit into our little carryon suitcase? Thanks
