Cancun Departure tax on Virgin Flight only

Hi all.
Not sure if this is the correct place to be answered....
We flying Gatwick to Vegas, few days sightseeing and a wedding then onwards to Cancun for recovery .
Whilst been to Cancun many times I have never just done a flight only with Virgin. Can anyone tell me if the Cancun departure tax is included with virgin flight only?
thanks

when i flew with virgin in 2013 to cancun the departure tax was included in the ticket price, I think its just Thompson that charge separately now. If i remember correctly if you look at the breakdown of your ticket cost it should say about the departure tax

Dummy flight booking shows Mexico airport departure tax £20.70 included

I think scheduled flights include the tax, charter ones don't.
