I'm probably closest than any of you - Houston - it's a 2 hour and 1 minute flight.
The last fare I paid for 20 May - 9 June was $588 taxes included -$20 +/- as I don't pay Mexican Tourism Fee because I am an FM3 holder. This ticket was bought months in advance.
When I first started going to PV in 2004 the fares were about $300.
I have been checking for New Years week (very flexible on dates) and they are $1200+ already.
I've gone RT from Salt Lake City cheaper than from Houston. One time I departed from Baton Rouge with a connection in Houston, then back thru Houston to Baton Rouge and it was cheaper than just departing from Houston !
I'd rather be hated for what I am than loved for what I am not.
