Shouldn't have problems with hold lugguage but hand baggage is a different matter.
For hand baggage ....
Knifes and solvents have been prohibited for a long time
Additionally since August 2006 there have been restrictions on any liquids (which includes gels and paints). The restrictions are slowly being relaxed but are still in place.
I have just come back from a business trip (London Munich) and can confirm that the restrictions are in place at both ends. In summary the restrictions are ...
Liquids, gels and pastes can be taken if their containers are less than
100ml each and can all fit in a litre sized transparent and resealable bag which has to be presented separately. The litre sized bag is abaout 8inch by 8inch.
Obviously these are the rules for UK and Germany - the rules are applied at the departure airport with no checks at arrival so you will need to check for actual restrictions at the airports that you will fly from.
Cheers,
Nigel
