On the 255 to LUN last night/this morning there were only 9 people in J, while WT+ looked as if it might have had three people in the whole cabin.
When we went to book this flight last year there was NO award capacity and fares were over the moon.
They even avoided turning the lights on until one hour prior to landing, it was so quiet... Which was nice but my 1:40 internal clock was set and so I was up early anyway!
