I will never use this excuse for a business again. I tried to book a flight three separate times to visit my family for Thanksgiving. Each time I entered my credit card info and "finalized the request", I was just redirected back to the home page. Thinking there was a problem with the website, I called customer service to see if they could book my reservation. I spent 30 minutes on the phone with someone who barely spoke English. We went through the entire booking process. AFTER he said we were confirmed, he then went on to tell me that unfortunately, the tickets are no longer available. This was the last remaining flight to see my family for Thanksgiving. His only response was "Sorry, unfortunately this happens sometimes."
