Direct flight for ease, combo for value

Samui's own airport is a garden with runways — direct flights from Bangkok take about an hour but carry a premium. The smart budget play is a cheap flight to Surat Thani plus the smooth bus-and-ferry combo, or the sleeper train if you'd rather trade time for baht.

Flight + ferry combo — 5–6 hours

Budget airlines to Surat Thani plus a joined-up bus and ferry to Nathon or Lipa Noi. Book as one ticket and the connections wait for each other.
