Are Austin Cinema Ticket Prices Rising Too Fast?

IMO it is OK for ticket prices to follow the rate of inflation.  But if ticket prices are rising faster than that, one wonders why.  I started buying tickets en masse in 1991, and I think they were $3.25 and $4.50 back then... may take some input from my friends.  (the Northcross Mall cinema was generally cheaper than that)  If my numbers are correct, Austin ticket prices have risen faster than the rate of inflation.

Using http://www.westegg.com/inflation/ - -

$6.75 in today's money, a matinee ticket, was $4.31 in 1991.

$9.00 in today's money, an evening ticket, was $5.74 in 1991.

If 1991 prices kept track with inflation, $3.25 matinee tickets would now cost only $5.08 !!!

If 1991 prices kept track with inflation, $4.50 evening tickets would now cost only $7.03 !!!

Additionally, some cinemas charged matinee prices all evening long on Wednesdays, I think in an attempt to generate sales.  That has gone the way of the dinosaur too.

Buying online was not an option in those days either.  Many cinemas are charging you money to buy tickets online (instead of offering a discount).  Pretty disappointing.
