Can't believe people are still moaning about social distancing when it comes to airports.. unfortunately there is a lack of staff within all areas of the airport as with most industries, many took the offer of redundacy during the pandemic. It will take months to even out with recruitment, even with this it'll still be challenging at times due to those having to isolate.
It will only get worse as traffic light system changes along with testing requirements in the future, not to mention seasonal Halloween and Christmas traffic.
My advice is if you need to travel, brace yourself for a few months... we will more than likely see queues out the door, limited opening of security channels, it's not going to be nice..
