I am reading this as a cost cutting measure and not an enhancment..... I for one do not always like to go to sleep at 7pm after eating at 5.
I think this is a very clever way of BA reducing overall costs but a lot of pax will see through it.
Doing this at the time VS bring out the new suite may not be a good idea.
Any BA lurkers want to be brave and come out to tell me/us we have it wrong??
