# Help for Air Canada Fare Calculation Example

I see the XT tax \$130.55, the fare calculation shows the break down, but it does not really match. As far as I know that ROE means rate of exchange, so 1.00 is the exchange rate.

However, if I sum up the rest of amount it is \$129.90, and there is still a difference of \$0.65.

• An exchange rate of 1.005 could be displayed as 1.00. This explains a 0.65 difference. – ugoren Jun 15 '17 at 19:34
• @ugoren there's no exchange calculation for which the rate could plausibly be 1.005. The current rate between CAD and USD is 4/3. Besides, the fare is explicitly quoted in CAD. – phoog Jun 15 '17 at 20:20
• @phoog, The OP mentioned a 1.00 exchange rate. I really don't know between what and what. Maybe CAD to CAD, and then 1.005 really doesn't make sense. – ugoren Jun 15 '17 at 20:27

The fare calculation should be as below. All in CA\$
452.00 fare
30.00 SQ
12.10 CA
24.71 (not shown) XG (5%GST of the above 3)
5.27 XA
9.32 XY
7.32 YC
47.94 US
7.46 AY
5.99 XF

Sum:
602.11

XT in their calculation is SQ+XG+XA+XY+YC+US+XF (no CA and AY) which comes to \$130.55

The Passenger facility charge for IAH is shown in both CAD\$5.99 and US\$4.50 at the end.

• Any idea why XG was omitted from the horizontal calculation? – Calchas Jun 16 '17 at 9:27
• @Calchas Only think I can think of is that it's a manual error. Why should that AY be shown in the taxes section instead of XG? – Berwyn Jun 16 '17 at 10:41
