Last Sunday I missed my connection in MSP due to delays of my prior flight. When we landed my Delta Android app showed me being booked on a later flight. I even could see my seat assignment. What a great feeling of not having to worry about rebooking. I was happy of how great it is being rebooked and knowing it without having to stand in line for an agent.

I stopped by an agent anyway because I found one who didn't had a line on my time killing walk through the airport. I was shocked when she told me that I did not have a reservation. Luckily she still could book me on that plane but the seat was much further back than the one the app previously promised me.

What's going on here? Why was the app showing me on a flight I don't have a seat. And why couldn't Delta automatically rebook me on the flight. They knew the plane landed and I was on it? How can I trust the Delta app ever again?
