Oct 30, 2015 at 6:59 comment added jwenting @DavidK I've seen both. Having dedicated carts for everything makes loading and offloading faster of course, having fewer carts that are loaded during the flight saves a bit of weight (but requires dedicated storage lockers for all the items, adding weight).

Oct 26, 2015 at 21:58 comment added David K Do they bring a cart on board that they use only for the duty-free stuff, or do they unload the leftovers from another cart and load the duty-free stuff on it in flight? In the latter case the fuel cost is only the cost to fly the actual items for sale, and if there are very few sales then they only need to stock the cart with a few items, so the added weight may not be much at all. But none of my international flights have ever had such a cart, so I have never had a chance to observe how they are prepared.

Oct 25, 2015 at 22:08 comment added user11933 Some passengers may never buy from a duty free cart on a plane, but will choose an airline that has one over one that doesn't. A duty-free cart might not make a profit in itself, but if it's helping to fill the seats, an airline will carry one.

Oct 25, 2015 at 21:27 comment added RoboKaren ^^^ I dunno, they carried flight engineers for several decades. :-)
Oct 25, 2015 at 20:56 comment added Simon It clearly is a benefit since it exists. Airlines would not carry additional weight with no benefit.
Oct 25, 2015 at 19:53 comment added mins "average profit from all sales must exceed ~$200", we are now in the opinion domain... who knows if sales from the cart must be profitable? Maybe there are other indirect benefits from selling these items.
Oct 25, 2015 at 19:51 comment added ROIMaison Seems like a lot. Probably airlines pay less for fuel?

Oct 25, 2015 at 19:49 comment added Sparkler @ROIMaison, so with 0.61 liter per kg, assuming 2 carts+items weigh 100kg, it's 61 liters (~$200). This means the average profit from all sales must exceeds ~$200.

Oct 25, 2015 at 19:20 comment added RaajTram This is more of an airline-to-airline based question, which might bring-in some opinionated answers. Needless to say, the total weight of the duty-free items would be negligible when compared to other weight on the aircraft.
