Nowadays, i allow 3 hours if i am changing planes. I just don't want the hassle of running to get the connection, missing it,trying to rebook, worrying about luggage etc. Singapore Airlines are good but a lot of other airlines are notoriously bad in these circumstances. It is the case that some attractive fares have short connections, but I don't go for them. I'd rather keep my blood pressure stable! Having said that, my Malaysian, Perth to KL flight, a couple of years ago, was 4 hours late and I missed the London connection. They met me at the door of my plane, in KL, with my rebooked flight and accommodation in the airport Hotel, with meals included. Very efficient. But I lost 14 hours!
