In general, the economy seat is just economy seat, unless you talk about AA, CX 10 abreast in 777, or compare with JL 8 abreast with 33 in pitch in 787... The SQ economy service I would say, it is consistent above average, which is the key points in service industry. The consistently above average will make anything become very good. But for the ground service, it is more depending on the contracted company.... After flew on different airlines via their outstation airport, I felt that it is always miss or hit when comes to the ground service
