We're flying Singapore Airlines to NZ - each time I speak to them they give me different critera for car seats. Most recent is anything goes (apart from rear facing) as long as they're not foam rubber. Prior to this I was quoted British Standard numbers etc. Because of e-tickets your don't get old fashioned confirmation itinerary. We're planning on taking our two Maxi Cosi Priori's for DS - 2 and DD 9 months - has anyone else done this and how was it?
