I'm going on a solo trip shortly for almost 3 weeks and I seem to be struggling with case weight (allowance 22kg).
I've bought everything toiletry-wise I'll need but due to it being mostly liquid, it's not leaving much weight for 3 weeks of clothes, shoes etc plus medication (I take a fair bit).
I know you can click and collect at the airport after security but that still means another bag to carry as it won't all fit in my carry on.
Do you take everything with you or buy it there? I don't usually have this problem but my breaks are usually shorter.
