33 weeks pregnant too late to fly???

Ok so my husband's friend gave him two tickets to the samifinal (soccer cup) in Chicago. The two teams playing are my husbands national soccer team against my national soccer team (chile vs Colombia) we are both die hard fans of our soccer teams & I was wondering if it's too risky to take a 2 hour long flight to Chicago to see the game live!! I'm so torn because that's been our dream for the longest time but never really wanted to invest the money in it, now that we got them for free is like once in a lifetime experience!! However I don't want to risk my baby's or my health? Any experiences on this matter?????? HELP!!
