Are you able to share how the codes are assessed? I'm wondering if it's multiple choice, fill in the blank, or something else altogether.

@SusanF95  no I cannot tell you how the codes are as I have not gone to Dallas yet. From what I've HEARD, they're multiple choice. You may have the airport code and have to choose the city, or might have the city and need to choose the code. This is just what I've heard and I'm sure it is always subject to change.
