So thanks to Google and it’s live traffic I can see Gatwick, Stansted, Heathrow and Birmingham have free flowing traffic almost to their drop off areas despite having pedestrian crossings to cross some of the lanes and then there is Luton which is now crossing free but with traffic queues now passing the Gypsy Lane road junction that is over a mile away. So what are all these airports doing right with there various designed drop off zones and Luton doing so wrong and who just can’t find a solution
(edit) Looking at my reference time of 6:10 I can see the queue is actually much longer than the queue for the old zone that has just been closed.
