IF YOU ARE A BRITISH:

1) Make your name change deed poll
2) enroll your deed pool at the Royal Courts of Justice
3) make an emergency passport
4) send that over to AA to change your ticket to your new name
5) attach your travel hacker's FF details
6) free checked bag
7) profit

IF YOU ARE AN AMERICAN:

1) tomorrow at 8:30AM, go to your local court and file a name change petition. Some locations will be able to schedule you with a judge on the same day
2) on monday, publish your name change details on a local newspaper, and take that to the judge on Friday
3) go to your local passport agency and get a same day passport
4) send that over to AA to change your ticket to your new name
5) attach your travel hacker's FF details
6) free checked bag
7) profit

Good luck!
