Hi, we are a family of 5 from the UK coming to Asia in August and flying with Cathay Pacific to/from Manchester and also with a couple of regional flights. All flights are in business class.

On our outbound flight, we will be arriving in Hong Kong at around 07:00 on a Sunday morning and (hopefully) connecting to the CX691 to Singapore, which is due to depart at 08:10. This feels like a tight connection but I was assured by my travel agent that it is doable and that the 1h 10m we have exceeds the minimum connection time at Hong Kong. Anyway, I’m just keen to find out what our chances of making this flight are (assuming the incoming flight from Manchester lands on time).
1) is there a fast track security for connecting passengers in business class cabins at Hong Kong?
2) is Cathay proactive in identifying and assisting customers with tight connections to move through the airport at pace?
3) worst case scenario, there seems to be a load of flights between HKG and SIN and ours seems to be the first of the day, so am I correct in assuming that we’d likely be re-booked onto a later flight fairly easily?
4) assuming we do make the connection, what’s the baggage system like at Hong Kong - how likely is it that our luggage will also make it on the same plane as us?

Sorry for lots of questions - I’m just trying to get a sense of how ‘normal’ this 70min connection time is and what I need to do to prepare for it. I appreciate that there will be lots of ifs, buts and maybes...

Thanks in advance.
