Flight 4215 from Pittsburgh to Raleigh, North Carolina on September 1st 2016 was a connecting flight where I had a 3 hour layover to follow. Due to the fact that the aircraft had to circle the airport more than once before landing, we had to divert to Virginia in order to receive more gas. We waited in Virginia for an hour and a half until we received gas and then once we flew back to North Carolina, we waited another hour on the runway because it was backed up and their was no room for our plane. This resulted in my friend and I missing our international flight to Rome. Once we deplaned, not a single worker addressed our problem with concern. As two students flying alone internationally, no one felt the need to address our problem with concern. The women working to redirect our flights was very rude scheduled us for 3 more flights the following day. This in turn forced us to pay for a hotel and miss the first day of our international classes. American Airlines did nothing in response to solve this problem and overall was the worst flying experience. Every time I have dealt with their customer service, nothing is properly handled and this is why I will no longer chose American Airlines.
