We were told that the increase in hours to 90+ was temporary.
Who said that, Panther?
I was at a training meeting the morning the increase to 92 hours prod threshold was made. Someone asked TCAS if it would be reduced back after the "crisis" was over, and after some pointed looking at his shoes, he said "I'm not going to make a promise I can't keep".
It was obvious that once gone it wasn't ever coming back.
