Basic taxi info TI to airport

Can anyone tell me what the general cost would be for a cab from Treasure Island to the airport? Also, do I need to say something about not taking a tunnel? I see it referenced a lot on here but can't remember the deal/I'm pretty sure I've fell victim to it before.

Thank you!

Estimated fare from TI to airport is $15.56.

Use that website to get a decent idea of Vegas fares to and from various places in town.

There's not usually a problem with getting tunneled back to the airport. If you want to give him the route, just tell him to take "Paradise".
