We finally booked our flight to Orlando directly through the Delta website. Then, after I purchased, out popped our seat assignments. On the flight down (from NC), 3 of us (we are a family of 5) are seated together. My DH is seated somewhere totally different and beside my mother's name it said "Not assigned". Okay, should I panic? What does that mean? Does it mean that they have overbooked the flight and she might not have a seat because getting bumped is not an option for us. We have a 3 and a 5-year old that would just not be happy campers in the airport for a different flight. I know that they give really good vouchers or additional tickets if this happens to you but we really don't want this to happen! Tell me if I should start worrying or do I need to call Delta directly or something?
