@Narelle ********
dear narelle - I wish to thank all those lovely people who offered suggestions & advice re my trip from Brisbane to SUVARNABHUMI in Thailand . Having very little info on the two pages of my flight ticket - ide never before been via tan son nhat a/ port in Vietnam - at Brisbane I waited patiently for the good / bad news - the lovely operator - looking at my deficient paperwork & her screen - gave me the fantastic news - YES, we can book your baggage through T S N to SUVARNABHUMI - it was like winning lotto - thanked the operator ( would love to have kissed her ) ide recommend this transit route to anyone, T S N a/ port is easy to negotiate yourself around & is well sign posted - SUVARNABHUMI is another story yet again
