(code name for exit row in Y) To be honest, I was not aware I could use the e-immigration gates. The chip on my passport seems to be playing up. Do e-gates require the biometric chip, or just a machine readable passport?
Good question. I suspect if you have a chip, even if it isn't working, at worst you'll get processed in a e-gate exception queue which will be no slower than going through the manual immigration process.
