Does it matter if I enter Thailand by land or air with a multiple entry visa?

When entering Thailand on a multiple entry visa (such as a METV), it generally does not matter whether you cross the border by land or fly. However, actual entry can depend on your visa type and your previous entry history. It's also advised to prepare proof of your travel history, especially if you are using the visa frequently. While both entry methods are valid, some users suggest that using land borders may result in fewer questions from immigration compared to air travel, especially if you have recently obtained multiple METVs.
