Glad to help! Just be sure to check with the carrier that they'll accept them for use, I know they're approved in Oz & US but not sure about elsewhere... you are talking about the CARES, right?? Not sure if carriers can also impose their own restrictions so would be worth a check befoore outlaying the $$$$$
On another point, DCS99 I hear what you're saying about crew using common sense, but we do have very little leeway- letting you know the child must be fastened in isn't us being mean or stupid (we can see that Junior is throwing a hissy fit) but we need to cover ourselves if a CASA/FAA inspector is on board... the crew member could get in a lot of trouble for not reminding you about the seatbelt sign, even if it's obvious the kid is protesting loudly. In short, I sympathise with the situation but I also need to do my job, or I could lose it. We know you're doing the best you can in that case...
