Plane tickets show you all included price including taxes/fee. It was part of 2012 regulation requiring full fare disclosure passed in 2012. Telecom/Internet providers ares ones that need to be fixed because companies like Verizon will charge you bogus "taxes" like a network portability tax which isn't a tax and they pocket the money.
Even then, there's other challenges. With Delta, booking a flight, I see a rough return airfare when I select my outbound leg, that then might be tweaked by my inbound leg choices.
Booking with Alaska, I get a fare listed that is only the outbound leg, and then I have to discover the inbound leg price.
This often gives the impression that fares are or will be cheaper with Alaska, and then after a few clicks, you realize that they're (mostly) the "same".
