Hi, need your urgent advice! I already bought the flight to New Zealand (round trip) via two airlines, 1st line with British Airways from S'pore -Sydney, 2nd via Sydney - Christchurch, but the booking is under one airline- British Airways,
1. When I do check-in in Changi airport with British Airline, can I do check-in for both and get boarding pass for both flights, and check- in the luggage all the way to Christchurch? Same for the return flights, can I check- in for both flights in Christchurch airport?
2. Is transit time in Sydney 2hours 45mins enough? Do I still need go through customs and security check?
3. Do I need a transit visa in Sydney airport? I am holder a Singapore passport, and the transit time as per the ticketing booking is less than 8 hours.
