On again... off again...
 

First time for me for this one... Boarded Delta in ATL for a 6:45ish departure. After 45 minutes of nothing, we hear that they are "rebooting the plane computer" to fix a maintenance issue. 30 minutes later, we are advised to leave the plane. Nothing TOO crazy...

Then ten minutes later they have us re-board... Only to have us leave again immediately after! Now they are "looking for another plane".

Seems crazy that they would have reboarded people without clearing the plane as being okay for flight, no?

Lots of fairly upset people. Wonder how many mileage or flight refunds this is causing. The group sitting next to me said they will be missing their layover now, and this delay will now cost me a $50 cab ride as my shuttle will have left me. :(

Sounds like an A320 to me. I've had this happen to me before, more than once. They seem to have frequent computer problems. Just my opinion.

Sounds like you are on a CR7/9.

I've had that issue a few times where they have a mx issue appear on their screen and then after they reboot it, it works fine. Sounds like they cleared the issue on reboot and then it came back after they boarded everyone and it was a no-go item.

It happens. Part of flying any airline.
