I wondered if you'd read LS@MAN's post properly. More time was spent checking in (30 minutes) by the handling agent than the total of 25 minutes for security. He didn't actually say the bag was rejected for no reason. He said no reason was given so presumably he didn't ask. Yes, it would be nice if check-in and security was no more than 30 minutes but given some of the delays in recent times, it didn't strike me as too bad an experience.
Yes, so just to clarify. The bag was rejected but I didn’t ask…as it was quiet and I wasn’t at all stressed, I personally decided against asking, the friendly security guy processing the rejected bags was working as hard and fast as he could.
The document checks at check in was the biggest wait…roll on when these are not required!
It was an hour in total from arrival at check in to I got into T3 airside…that did include a stop at boots.
