Funny you mention about guard... I always hear people yelling at others on guard, but have not once flown with a DL pilot who jumps on others on guard.

Yet, even on guard, whoever it is will mention about delta pilots jumping on them. I'm pretty sure it's very likely other parties convincing themselves of what they believe to be true.

The only thing I've ever done on guard is confirm that the offending party's gate is occupied.


Speaking of, I heard a hilarious back and forth recently with a UA flight in EWR asking for MX at their gate. Totally uninterrupted, the guard troll assured them that they had their problem noted and will be right out.
