In October, I booked tickets through the Delta groups desk for my 19 students and me to fly PIT-ATL-FCO in May ($1,186--not too bad for RT in May given what I've seen happening recently). Fast forward to last night when I was looking at my flight on the Delta app. It alerted me to a change--a scary change. Our 12:43 pm flight from PIT to ATL was moved to 1:55 pm which gives us a whole 46 minutes from when we land until when our flight departs for Rome at 4:25 pm. (Delta added an 11:14 am departure, but the system booked us on the 1:55 departure for some crazy reason.) I called Delta first thing this morning and the agent agreed that we'd likely not make that connection. I'm waiting to hear back from Delta, but there is space on the 11:14 flight and the agent put in a request to move us to that. I'd much rather have a 3.5 hour layover for the group. I'd even balk at the 46 minutes if I were traveling alone.
All this to say, when the agent looked up our booking she first responded, "You're on the 12:43 flight." "No," I replied. "It doesn't exist now." She responded, "Ah. We have two systems. Let me look in the other. Yes. I see what you're saying. The 12:43 flight no longer exists." I couldn't resist--these people have hard jobs: "I bet that's a pain for you." I won't tell you how she responded. Lesson learned. This could be a group booking issue, but I thought I'd share it with this community. I appreciate all of the wisdom and camaraderie on these pages and wanted to contribute what I learned because you never know!
