Do you need an exit ticket to enter Thailand on a US passport?

To enter Thailand on a US passport without a visa, you are technically required to have an exit ticket within the 60 days granted on arrival. However, in practice, immigration officers rarely check for this requirement. Airlines are more likely to request proof of onward travel, so it is wise to verify with your airline. Some travelers suggest purchasing a cheap refundable ticket to a neighboring country just in case, as experiences vary widely among individuals.
