I did not want to start yet another mud slinging thread about a carrier
I quite agree PAXboy, which is the reason why I have not mentioned a carrier name.
It might be worth putting into the letter to the carrier about the 'lifejackets in o2 stowages' as their is a (hopefully very) slim possibility that not all their crew are aware of this fact - and the carrier can issue a memo to all crew advising of which aircraft in the fleet have the lifejackets under the seat and which are in the o2 stowages.
