What happens if accidentally use my maiden name when buying my flight ticket?

If you have accidentally bought a flight ticket using your maiden name, and then changed your name after marriage, you will need to contact the airline and provide them with the relevant documentation (such as a marriage certificate) as proof of the name change. Some airlines will make the change for free, however, this is normally decided on a case-by-case basis.
