I am sending 5 people out to Irvine California for business. Price for tickets had been $440 for the last month. This morning the price was $370. I booked one and then logged on to book the other one. The price was back up to $440 within minutes. I called to complain and the guy gave me the same $370 price. Got to the office to book the other 3 and the price was back up to $440, so I called and this time refused to help me out. Trying to give them another $1000+ to travel and I got ZERO help. It is amazing how little Delta cares about their customers.
