Guaranteed, no. Very little in this business is guaranteed. However, ancillary revenues can in general be forecast with a reasonable level of accuracy based on historic performance of a route, PAX mix (first class vs. business vs. premium economy vs. economy, etc.), stage length, seasonality, etc. I don't know why ULCCs would be any different; in fact, I would guess their revenue analytics guys/gals are pretty proficient at this stuff.

I think the TSB is missing the point: if people aren't complying with evacuation instructions being shouted at them during an actual emergency, they aren't going to pay any more attention to an amended pre-flight safety briefing than they do now. It's just going to take a bit more militancy from the folks trapped at the back of the aircraft directed at the oafs up front who are blocking the aisle while they recover their baggage. Should I ever find myself in that predicament, rest assured that any veneer of courtesy is going to go out the window pretty quickly.

Wow - 14 months/2X as long as planned for a 400-hour check? It'd be interesting, given our own upcoming procurement, to know the comparable figures for the F35.
