It would be pretty hard, but...you can do a lot being polite, confident and appearing to need help with a mix of misdirection.
Get through the metal detectors with a folded up piece of paper that looks like a ticket. Get there with a big crowd. Go to one end of the ticket scanners and then move down the line, don't try to offer your 'ticket' for scanning, just keep walking past busy and irritated scanners, cutting through the crowd. Maybe throw out a 'sorry' or 'sorry...my wife' if needed. Look a little confused, like you are following someone who is changing their mind or took a wrong turn. Look for a ticket taker/scanner who appears pleasant, busy, kind, maybe old. When you find the right one, slow down while she looks up and you say with a mix of confidence and apology, smiling and in a hurry, "she scanned me back over there, I'm just catching my wife". Vaguely point back at a mix of scanners you passed, and quickly toward and point to your non-existent wife as you say this. Move past the scanner into the game. Say 'thanks!' and wave your 'ticket'. If she says anything just keep moving and say, "thanks again! help them. (point at people now waiting) I'll get my wife". Big smiles, wave, like she is an old friend you were happy to run into and keep moving toward someone turning a corner who could be your wife. Turn the corner. Take off your hoodie and hat or some other outer layer, just in case.
Maybe you get in. Maybe you get tackled and arrested.
There are some other tech-savvy ideas but I don't want to contribute further to your delinquency. Just donate some plasma for cash, sell some stuff, find a job agency that hires out day labor and buy tickets.
