FLB: having been down route too often with an APU that is u/s I agree with you totally. Fortunately the airline that I flew with was too cheap to take out the blinds! Low cost airlines (I'm sure that you know this already) spend too long looking at the bottom right corner of the spreadsheet, and can't see the intangible benefits or damage caused by certain decisions. They can be remarkably short sighted, hence our profession and industry in this country being in the parlous state that it is in.
