If you have a long haul connecting flight on one ticket
for example Sydney to Singapore and then connecting Singapore to Rome), is check in open 48 hours from the first flight or 48 hours from the connecting flight time ?
With Qatar Airways it was always from second flight , but I have read that with Singapore Airlines check in is open 48 hours from first flight .

Do Singapore Airlines have USB or USB-C charging ports on the airplanes (eg seats ) ? As you cannot use power bank I am considering this .
