As you are highlighting, there are different costs depending on where we go. In many cases there are costs that we can control. In some cases there are costs that we cannot control. We're often found with only one caterer that's available that meets the standards we require and the health and safety requirements for those who are on board.
As per any cost, what we find is that there are five factors. There's the cost of the food, which is a protein, which is typically between $23 and $90 total. There's a tray set-up fee that goes on top of that, which is sometimes the same cost as the food. The tray set-up fee includes the bun, the salad that you would get and the small dessert that goes with it. Beyond that, there are food and snacks, which, as we've highlighted, we are only going to be purchasing now in Canada moving forward.
There's also a component of what we call “overages”. As described by Mr. Wheeler earlier, we're only buying a 20% overage at this stage. We used to buy a 65% overage. That gives that option for the front crew, as was mentioned, for the passengers. Then there are back-end fees that could be sometimes up to 20%. In this particular case, it was 50% of that particular leg that were back-end fees. Back-end fees are handling and delivery, they're storage, they're cleaning and disposal of international waste and they're taxes.
When you add all that together, all of a sudden it becomes a much larger bill, as you've described, so we're always looking at value for money and making sure that we're going to caterers who will provide the best value for money. I would also say, as highlighted by Mr. Wheeler, going forward, we're not going to be working with Global Affairs Canada on any changes to the menus that are offered by the caterers. That's really going to drive down, we believe, the prices, but there are certain things that we will not be able to control. Some of those things are the back-end fees I described and the tray set-up fees.
