Now separate immigration would be a TRUE luxury - only experienced it once, arriving at Macao by helicopter - the copter passengers got their own, much-needed queue, which saved about 45 minutes...
Fly to Dubai with Emirates, you'll get it every time, in F/J.
When you get to silver level in Skywards, they'll give you your own electronic pass and you won't have to see an immigration officer at all.
But of course, you'll happy to slum it with everyone else, as it would be a bit embarrassing to receive preferential service, wouldn't it?
