PomPax, 3 or 4 empty seats next to each other on Long haul ?
Which airline ? I will change my booking plans next time
A cheap way to avoid being trap in most CAT ( but not all ) would be to use wind reports from preceeding aircraft IRSs , downlink those to a mega computer which will calculate and display where the core wind is and therefore indicate the areas of possible CAT ( generally only on one side of the wind core ). You could uplink the picture at regular intervals and crews could avoid those areas.
