How on earth as a passenger would you know that the attitude of the people who drive the things has changed? Do you spend a lot of time on the flightdeck talking to people?
My issue is with you calling people "old farts" when they are nothing of the sort.
There is a lot of uncertainty within the company, mainly because no-one is really sure who's making the decisions and what is going to happen in the next few months. However, I've certainly not noticed any change in how customers are treated and I fly on our aircraft as pax at least twice a week. Of all of the people I've worked with over the years, the people at bmi really do stack up at the top, they do a fantastic job in often trying conditions.
I wouldn't blame them if they were a bit jaded at times, but somehow the vast majority aren't.
I've found the flight deck crew a pleasure to work with and easily the most flexible of any pilot workforce I've seen. So I think it's extremely unfair for you to label them as inflexible old farts.
