The name on my ticket is misspelled or wrong
It is important to be careful when you fill in your details and avoid typos or mistakes.
The typical procedure for changing a reservation is to cancel the issued ticket and book a new one with the correct names.
In domestic routes, the authorities are not too strict regarding misspellings and it is unlikely that you will encounter a problem upon ticket control.
Please note that on international trips, you should be more careful. Passenger names should be identical with the travel documents used to travel, or else passengers may be denied boarding or will be asked to pay a new ticket.
