Another datapoint, due to delays at MAN last month, our 2hr connection at SIN turned into 45 mins, basically enough time to disembark and walk the length of T3 to board PER flight. As it turned out, all MAN passengers’ luggage misconnected so were loaded on the next flight and couriered to home next morning, so although frustrating at the time, worked out well.
Plus you get to claim travel insurance that kinda subsidises your trip!
