This is a record low, should I jump on it?!
Might be worth noting that despite seeing my selected C+ seat I get the friendly yet slightly panic-inducing message next to this offer of: "Advisory Message:Uh-oh! We're sorry but we are not currently able to assign a seat in your class of service. Seat availability can change, so please check back later. If you do not have a seat assignment, a seat will be assigned at check in or at the gate prior to boarding."
