Hiya mgmark7,
I travelled last month to Amsterdam, through KLM airways.
We went from Manchester Airport, when handing over out baggage, we showed the person behind the desk what Mike had in his pocket, and I had in my handbag. they were the clear TW 5 ml bottles. He said they were fine, and no questions asked. also had 2x 30ml bottles wrapped carefully in our luggage, incase we couldn't carry it on our person.
We had no quibbles at all.
Every airline I'm sure would have different policies, but this is just my findings so far

Have a good trip

Ellen
