I'm not sure if this is where to post my question, but I am talking to this girl who went to school with me 12 years ago and lives in Santiago, she wants me to visit her, but I don't have the money. I would be flying from Philadelphia PA, or NYC, USA. Now, I could save up for it, or I could try to use my friends buddy pass. The things is, he works for US Airways which doesn't travel to Chile. I don't really understand how buddy passes work, I've only flew once. What I'm wondering is if you can still get a discount on a flight?
