I think that it would be a useful and time saving feature to have the ability to automatically drag out switch-back queues at check in and security. It would be like dragging out a secure area or room, but instead a queue.
Why should it be implemented
At the moment it takes a lot of time to drag out every row of queue for each hour desk for a simple switch-back and let’s face it, it’s not the most interesting thing to do in the airport.
There should still be the option to draw the queue like it is now for those who want irregular queue patterns.
