1. There is a lot of time between now and next week. Don't panic. Jordan is evacuating its citizens from Egypt right now.
2. Do not fly into Cairo. No matter what.
3. AA may be able to help sometime, but probably not if you bought the ticket from RJ.
4. If you bought the ticket on a credit card and RJ cancels the flight, dispute the amount with your credit card company, as RJ would have failed to provide what you bought.
