50mins! last two i did were around 35min airborne. with 10 mins up and pre landing, that left 10-15mins for service with up to 98pax. I think the bags are a good idea. At least you get something instead of watching the trolley get to two rows in front and then hearing those magic words "10 mins to landing!". I think the crew do a great job to do a service on such a short flight.
