hi biglez..there was a similar post to this yeaterday on another forum.
check the regs.
is it not the case that it was agreed that if you had to transit...and had purchased in a duty free shop ( only) somewhere alon the line on tghe same day ( do'nt ask me how the dateline problem comes into this) and if you had the bottle sealed with the receipt ( it does'nt have to be in a clear plastic bag as that is only for 100ml liquids brought from outside )...then you are ok..
i may be wrong but thats my understanding of the rules...of course it still has not fully been implimented in some countries...but i think i am correctr...
otherwise who would buy anything again in a duty free shop unless doing a single hop flight..
''rues is rules'' ..but business is bussiness...
