Just a quick word for those trying to reserve bubble seats. We did this yesterday and WERE first off after 1st class and PE. I managed to get my family out of the bubble first. No immigration dramas like people have been suggesting. May be we got lucky but it was empty when we arrived, every booth was open and the cases were out fast. Took me 35 minutes from the plane doors opening to boarding the magical express

Much faster than indirect and doing immigration elsewhere for sure.
