Thanks for the input
It was NOT the final letter of the name, to be clear the last name is Quintanilla and the reservation name is Quintailla....hence, just missing the second "n" as a typo by the agent. Since it sounds like others have has similar issues and just winged it with Asiana specifically maybe that is best??
I could ask US to pull the call recording because due to the length of the name we spelled it for the agent twice .... But im not sure I want to get in the weeds on this if it can be easily sorted at the airport.
