I haven't found a clear answer to this online; hoping someone can help.
Traveling to 5 different destinations: Hong Kong and 4 others within Thailand. Point of origin is east coast USA. It seems that booking one ticket with Cathay Pacific and then multiple one-way tickets with Bangkok Airways within Thailand is about $250 cheaper than putting all flights for both airlines on a single ticket.
Apart from the cost difference, what are the advantages/disadvantages of booking one ticket vs. multiple?
