Strict — Routinely Enforced, Often at Check-In. One of the most notorious destinations for this — airlines routinely deny boarding without proof of onward or return travel, and immigration can also ask on arrival. One-way travelers should book a refundable onward ticket or use a proof-of-onward-travel rental service.

Thailand routinely enforces this, often right at the airline check-in counter before you even board, not just at the border.
A return or onward flight, bus, or train ticket showing you'll leave before your visa/entry allowance expires. A fully refundable booking works too — many travelers book one and cancel it after boarding.
A fully refundable flight booking (cancel it after you board) is the simplest fix. Proof-of-onward-travel rental services generate a real, verifiable-looking reservation for a small fee if you have no fixed return date.
Enforcement varies by airline, individual agent, and your specific visa/entry type — this reflects general patterns, not a guarantee either way. If you're traveling one-way or with an open-ended itinerary to anywhere rated inconsistent or strict, consider a refundable onward ticket or a proof-of-onward-travel booking service as a low-cost safety net.
