Will a one-day overstay in Thailand cause me problems at the airport?

A one-day overstay in Thailand is generally manageable, especially for departing travelers. Most users advise that at airports, the fine for a single day of overstay is often waived, and you will receive a 'fine waived' stamp instead of an overstay stamp. However, while leaving, it's wise to ensure you go through immigration and customs by midnight to avoid issues. Future travels may be scrutinized due to the overstay stamp, so it's best to avoid overstaying whenever possible.
