Well it is the DL forum, someone would complain about Low award availability showing on the award calendar.
At the risk of being the skunk at this garden party, Delta's risible "award calendar" has long displayed Low award availability; this is the come-on.
What transpires when one goes to book said Low Award is where DL's unique suckiness comes into play. Does it choke? Seats sold-out? Cannot book online and should call?
Delta's IT dolts have long figured out how to work a color palette; making the leap from putative award availability to booking the ticket has thus-far proved elusive to this modesty talented group.
