DO NOT UNDER ANY CIRCUMSTANCES USE JUSTFLY! I am military and my orders changed last minute. My flight home needed to be changed and they were going to charge me $5,738 to change my flight. The only other option was to cancel and only get a partial refund 6-8 weeks after the holiday. I was just on the phone with them for 3 HOURS and getting the run around. I was transferred to about 6 people, the last one being the only one without a language barrier issue. Each time I was transferred I had to reconfirm my identity and re-explain the issue. Very infuriating. I sent them a copy of my military orders to prove they just changed and no one would help. My advice is to just pay the extra money to book DIRECTLY with the AIRLINES! DO NOT USE JUSTFLY EVER!
