Well, we're sitting at a remote gate at IAD, diverted from DCA. AA won't bring a people mover or let us off the plane. We're to be refueled and fly to DCA. It's now 30 minutes and no fuel truck in sight. No ETA. And they had 20 minutes from decision time to landing. Captain says OPS refuses to bring people mover.... so we're stuck. I get weather delays and diversions. It happens. But this is bad handling of irops. There is simply no excuse to not get us in ther terminal and either let us get cabs or bus us to DCA.
