Hopefully, they’ll be able to work that out and hire more people with that many more passengers passing through the system.
One would hope so.
Heck, I would be happy if they just staffed appropriately. Passport control is like the bank, lots of windows and hardly a person manning the desk. Thing is, it’s not like they don’t know when all these international flight arrive, they simply appear to not care.
Let us hope things improve.
