I agree....Total price should be shown, but taxes and fees should be spelled out.
As a matter of fact maybe someone can help with this. Why taxes & fees on exactly the same route BOS-Toronto round trip, are different for Porter and Air Canada with the exception that Porter flies into Toronto Island while Air Canada flies into Pearson (with one of the most expensive landing fees in the world). Taxes and fees are $117.49 on Porter and $72.99 on Air Canada. Makes no sense to me.
