I'm a long time SQ patron. For good reason. Had a similar trip last year and took another airline (at that time, price was the main factor). This time I took SQ as they had really good rates. No comparison. Dependable, reliable service and excellent aircraft. No issue with my special checked in item (a guitar that had to be handled differently) on my way to my destination (not this flight). In the previous mentioned other airline, they misplace my luggage upon arrival. After spending about an hour (with no effective help from that airline's agent), I managed to find it at another belt!
