Crew did the best they could but I am sure were embarrassed to work for Frontier

Flight was over 31/2hours late and took off at 1:25am. I received a $15 food coupon for my inconvenience and nothing was open to even get water and your airline told me I could use it when I land at 2:30am in Chicago..give me money off charging me for my seat and my luggage for this inconvenience. I arrived in my home at 4:00am and I have work to go to today after 2 hours of sleep!

Flight was late leaving DC, was late leaving Chicago (mad had a gate change that wasn't announced), and when we go to Austin had to sit in the runway for 20 minutes due to someone else at the gate.

They had no record of this portion of my trip, after a few people checked they found the Chicago to Ammon part so they added me onto a flight from Washington to Chicago. All should of went well from there but they sent me to the wrong gate. Luckily I just made it to the correct gate for boarding. Upon arriving at Chicago there was no one available to provide information on how to get to Royal Jordanian gates. Also on my AA portion of my flight coming into The U S in New York the flight was cancelled and I was told the next flight Available was next day (18hr delay) at the other NY airport. I had to have someone drive from D.C. (My destination) to pick me up
