I had a trip to Cabo in 2011 and began packing on Saturday to leave on Tuesaday. I soon realized my passport was MIA. I live in San Antonio and drove to Houston to the passport office on Monday and was there when it opened up at 8 AM and had it by 3:00 that day. If you live by one, you may try to just go by there and have one made. I would print off the airline ticket as proof.
