The issue of "intro fares not available on the RJ flights" seems to be fixed.

Here's the lowest new intro fares from MBL in bold, compared to the TVC fares I found yesterday. (I checked yesterday for a relpresentation because competitors might match F9 into fares.)

LGA $417 $190 intro $270 post-intro
DFW $472 $230 intro $290 post-intro
DEN $423 $230 intro $370 post-intro
MCI $419 $190 intro $250 post-intro
LAX $443 $230 intro $330 post-intro

And here are a few samples from RHI with F9 fares in bold:

RHI-DEN $403 $238 intro $378 post-intro
RHI-DCA $383 $238 intro $338 post-intro
RHI-MCO $397 $238 intro $378 post-intro
RHI-LGA $363 $198 intro $278 post-intro
RHI-BNA $351 $195 intro $338 post-intro
RHI-BOS $363 $238 intro $338 post-intro

Finally, DLH compared to IWD with F9 fares in bold:

DLH-DEN $341 $238 intro $378 post-intro
DLH-DCA $391 $238 intro $338 post-intro
DLH-MCO $331 $238 intro $378 post-intro**
DLH-LGA $401 $198 intro $278 post-intro
DLH-BNA $383 $195 intro $334 post-intro
DLH-BOS $421 $238 intro $338 post-intro

**may not be correctly loaded as most days are in the $600-700 range round trip...the $378 was one particular pair of dates. Most other intro and post-intro fares were the same each day of the week.

In most cases the intro fares are much better than typical, and often the non-intro fares are at least a notch or two better than typical. Hopefully these markets respond to the much-improved service, in reliability, speed, scheduling and comfort.
