Can I leave Thailand with an expiring visa if I pass through Immigration on the last day?

The user asks whether passing through Immigration at the airport on the day their visa expires is sufficient for them to wait for their flight the next day. Responses indicate that as long as they go through Immigration on the expiration date, they should generally be fine, and that there is commonly a one-day grace period for overstays. However, some comments suggest that the timing of the flight may affect this, particularly regarding check-in procedures.
