If BHX truly has aspirations of growing and expanding their capacity, they need to have a look at how they deal with a number of flights arriving at the same time (not an uncommon occurrence I would think). Came back this lunch time to queues for immigration snaking down the corridor above arrivals, with the arrivals hall stuffed to the gills. Looked out the window to see pax off a flight queuing on the tarmac as they couldn't even get upstairs! There were half a dozen police downstairs keeping the peace which is rather telling...
Got into baggage reclaim to see every belt going, full of baggage which wasn't getting picked up as everyone was trapped in immigration! On my belt there were four flights worth of bags, so many in fact that they ended up blocking the belt in a massive heap!
Not a glowing endorsement for expansion...
