I was Operating crew last week on a 22:10 departure (From T1).
The staff channel that we take via T3 was closed so we headed up to the Pax channel. They wouldn’t let us through as apparently she “wasn’t authorised to let crew through”!
We we had to go back to T1 and through pax channel. I’ve emailed the relevant department but don’t expect any response. What an absolute joke this place is becoming !!
