American Airlines today announced that after reviewing the Federal Aviation Administration (FAA) policy on raft capacity (which mentions that the rafts on the plane should accommodate for all passengers, crew and lap children), they found that the Boeing 767 fleet was not following the policy. So, temporarily all flights using the plane will be restricted to 228 instead of earlier capacity of 236 (both number includes the crew of 11). The airline did add that it was never safety concern, since the the seat cushions could be used as flotation devices instead of the raft.
It seems that the Hudson river landing of flight 1549 had caused the self check.
The airline is going to add additional rafts to the planes for permanent solution.
What it means the passenger?
For long term, the airline might restrict the number of seats that it can sell and for the current flights, the flights which are sold between above capacity and capacity-8 might be looking for volunteers to fly some other flight, if all passengers show-up.
