I recently traveled with my 3 month old daughter from CVG to LGA and back. Ok, I'll admit it, she was great. Withstood a 2 hour ground stop at LGA w/o crying...she just slept. (OK, so I am pretty proud of being a first time father...so what!!?)
Anyhoo, when we got to the gate the monitor said something about notifying the agent about having an infant in arms. (Seemed logical to me so they could account for her.) When I went up to the gate agent he took me and my wife's tickets and reassigned our seats. We were flying a CRJ900 and were informed that we could not sit on the left side (A,B) side of the plane b/c there was not an extra oxygen mask for an infant. This was news to me.
Where in the heck does one find these things out? I like to plan my trip and pick my seats. Unfortunately, it seems since DL has turned CVG into a a hub that only flies regional jets we will run into this issue more than not.
Are all RJ's/EJ's built this same way with the 3rd mask only on the right side? What other nuances are inherently different from "regular" planes to "regional" jets.
