No, you're wrong. BZZT, BZZT! (See, I can do that too..)
Your claim was about SHORT haul coach. So, yes, the UA A320s and 319s have 18", but as you are surely aware, the 737s and 757s all have 17". So until those Boeing planes are retired, it's still usually 17". Your reference to the 777s and 767s is also misplaced, because these planes are usually used for long hauls (e.g. to Hawaii) and not for short hauls.
For AA, yes, they have 18" on their most common domestic plane.
But you've neglected to mention DL, CO, and NW, each of which probably has as many flights as all 3 of the smaller airlines you have chosen to focus on (JetBlue, Frontier, Virgin America??), combined!
For every US, there's a CO. And for every JetBlue, there's a Southwest. So, no, it's still not usually 18".
BZZT, BZZT!

All of the UA airbus planes are 18, so are the US 777 and 767's, the EMB170 REGIONAL JET has 18.25....
American Airlines:MD80 (their workhorse for most domestic coach)...18"
Even their 757/737 are 17.2" as opposed to 17.
AC also has 18" on their EMB fleet and their 319s
Jet Blue: 17.8 (320)-18" (E90)
Even USCrapways has 17.5-18.25" seats on the Airbus/CRJ/EMB planes.
Frontier? yup you guessed it: 18"
In reality only the older Boeing planes have 17"....
VirginAmerica.......in COACH......19.7"
