[QUOTE=bmvaughn;10120062]I'm asking about UA, specifically. From my experiences, in
almost every state, both goods and services are taxed - so yes, attorney, hairdresser, manicurist, etc (although health care seems to skirt under the radar if it's non-elective in many states).
I suppose my question would be more pointed if I had asked whether or not UA was figuring this out on the backend and paying the state, rather than trying to adjust prices on the front-end to take state taxes into account.[QUOTE]
Missouri does not tax services.
Can you cite a specific instance where UA has NOT passed along a tax and chosen to eat the cost?

What makes you think UA would pass up an opportunity to charge more?!
Actually, I am surprised that UA doesn't charge a "tax handling recovery fee" to fund the cost of collecting and paying taxes on airline tickets.
