My concern is more about the ability to bring liquids than timing (I have over 1.5 hrs between flights, which should normally be enough unless there is a very severe delay to the AF flight). The bottles would be bought airside in the EU so I suppose I should in theory be OK as long as they are properly sealed in the appropriate bag by the shop at origin but I wonder whether standard landside security might nonetheless be difficult. I would not want to have to throw away circa £100 worth of goods due to security objecting to my bringing liquids from landside, even if in a sealed "duty free" plastic bag.
