So I'm a dummy. In my excitement to book our honeymoon, I accidentally put FI down as Alex lastname instead of Alexander which is is full name. We've flown togethre before (but not out of the country) and his ticket said Alex then too. We had no issues. But now I'm afraid of us getting to Cancun and them not letting him in or something dumb like that because of the names not matching. From what I remember, the only time they match the name to the ticket is when you're checking in at the first airport (which is the same airport we flew out of for NY). So I FEEL like he should be okay. Is this something I shouldn't worry about because it's clearly the same person (last names are the same and the first names are clearly the same, just one is shortened), or should I call them and have them change it and possibly incur a huge charge to change the name on the ticket?
WDYT?
