I don’t often fly so this may not be news to those of you who do....
I got hauled over in Stansted as I had 2 plastic bags of liquids etc. One of which was spatone and meds of one sort of another. Oh no, only allowed one bag (sure we had no problem with more than one when flying to Italy earlier in the year...). Had to prove I was a cancer patient....I’d taken everything out of the boxes to save weight with Ryanair.
I was told that if you have the prescription you can have an extra bag. This would have saved a lot of time. So next time, keep it in the box or take a paper prescription or doctor’s letter.
