Nobody has posted it on this forum, just like nobody has posted the average SWA FO income - probably b/c nobody knows for sure. I can't fix your problem with the lack of an AirTran # (I don't know it either), but the SWA #'s are known.

Captain Carl Kuwitzky and SWAPA wrote a packet for AirTran guys about Southwest and SWAPA during the 'courtship' phase. SWAPA #'s about themselves, which I've quoted below, are certainly pretty accurate:

• Industry leading B737 Pay Rates. SWA Captains average
  over $230,000 and First Officers average over $140,000.
• Approximately the last five years, SWA pilots averaged 105
  “Trips For Pay” (TFP) per month, or about 1260 TFP per year.
• Approximately the last five years, SWA pilots
  averaged just over 18 days off per month.

The most junior ATN CA on the property has a min guarantee of almost $138K ($151 x 76 hours x 12 months). If this CA can pick up just 2 hours of credit per month, he/she too is "over $140,000".

The most junior ATN CA makes at least as much as the 'average' SWA FO. An "average, fly your line ATN captain" makes more, since this CA has a higher hourly rate, flies a line, and likely enhances their month for some additional pay, just as the average SWA pilot does. Remember, the 'average' ATN CA is around 25% on list @ ATN. Thus, when this 'average' CA becomes a SWA FO, they will almost certainly take a pay cut. In the same way, those ATN CA's who do get back to the left seat at SWA will see a pay raise for the same reasons - the hourly pay rate differences.

Those are the facts, backed up by independently verifiable numbers. Please respect the results.
