I'm not the most organized person. My Russian fiancé and I had a wonderful trip to Mexico last month, and I'm pretty sure I crumpled my boarding pass up and threw it away along with some other trash in our AirBnb. Then I was given a small receipt after I got through the airport in Cancun instead of a stamp, and I forgot it when it was time to depart. I had to go to some office there and fill out a form saying I didn't receive the stamp on my passport, and when I asked if I get a stamp after that they said no. I got home, didn't think about filing the petition for awhile, and now I don't know where that form is. Or my return boarding pass. I have flight receipts but after reaching out to Spirit, they can't send me a copy of old boarding passes. I have the AirBnb receipt, I have transactions in Mexico, pictures, my fiancé has his boarding passes...how screwed am I?
