On short haul, it is a real problem for carriers - especially those that want to offer a 'full service'.
Increasingly, I hear the f/c announce that c/c may commence duties but expressly telling pax to stay put. C/c are then out of seats like bullets.
Last week I was on a BA 'ultra' short haul. Sector is always stated as being an hour but, on LTN~IOM in the 146, wheels-to-wheels is usually 50 mins, giving c/c a big problem.
On this occasions, the w-2-w was 45 mins and they managed to get bar service and tea/coffee/snack trolley done and dusted!! To be frank, I don't know that it's worth it. One trolley run is more than sufficient on such short sectors. The c/c did very well - as always.
Let's keep the c/c in their seats until we are well established, say Fl500? But, in the domestic UK that would limit service time and the full service carriers are too desperate for that.
I would rather they just did the bar service (forget the weak tea!) and reduce the price of the ticket.
