Thanks. The odd thing is that Finnair have been very proactive in giving the lifejacket. Maybe that was an abberation or to show they had them !
Thank you for the clarification that it is not mandatory. The carrier in question may be relegated on my list in this case until the infant is in its own seat and stool (AIUI "car seats" open a world of worms as well).
I don't know whether the belts are helpful. They always look flimsy but I guess anything is better if the pilot has to brake suddenly. After all, even at coming to gate people can come off balance with light braking and people are told they cannot have books etc by some FAs on TO/landing due to the risk of things flying around the cabin. I would have thought a 9kg infant would not be the best thing to have flying around for both infant and passengers.
Again ! My thanks.
