Some of both. WT has constantly alleged (incorrectly) that AA is over-staffed compared to DL and UA but he refuses to take the much-larger Envoy into account. UA has no wholly-owned regional feed and DL's wholly-owned regional feed is much smaller than Envoy.
In addition, pmAA hasn't outsourced as much ramp and maintenance as UA or DL.
If he were intellectually honest, he'd argue that AA should outsource more so that it can match UA and DL. But intellectual honesty is very difficult (nearly impossible) for WT, as he constantly shapes his posts and alleged facts to fit his narrative.
Of course new AA (pmUS and pmAA) is slightly over-staffed, as it has yet to layoff all of the duplicative workers - that will happen as the two carriers are combined.
except that DOT data does show what percentage of the employee base is for each type of job function as well as for mainline vs. subsidiaries.
Yes, I know that AA has a larger regional carrier and also does a higher percentage of inhouse maintenance which inflates its numbers but just between 2012 and 2013, AA's percentage of outsourced maintenance went from 25% to 30% in one year. DL's percentage is at 40% for 2013 and DL sent nearly all of their cabin mods out to contractors.
AA/US still have two headquarters and there are duplicate staff in fairly large overlap cities like LGA, LAX, and ORD. There are duplicate res offices. We had a thread on here about the duplicate lounge personnel at LAX.
And then there are still duplicate hubs which will be resolved one way or the other. AA/US has duplicate internal competing hubs just like UA/CO had between CLE and ORD, EWR vs IAD. AA simply doesn't need the amount of duplicate hub capacity on the east coast - 4 hubs have some form of hub status and also have flights to Europe.
And this doesn't hold true for DL??
of course it holds true. WeAAsles gets it that there will be a move by each carrier to move into each other's strength areas while trying to protect their own and they will figure out ways to carefully carve up the market where it is obvious the other network carriers are coming and they might as well protect the market between themselves rather than give it to the LCCs. to a great extent, that is what AA and UA did between LAX and ORD.
But AA is smaller in BOTH Asia and Europe relative to DL while Latin America is the smallest of the global regions (Europe/TATL, Asia/TPAC, and Latin America). the relatively little amount of int'l growth DL must do to have at least a #2 presence in each of the global regions is less than what AA has to do to get to the same place.
As much as some people act like it is all personal, it is simply a result of the fact that DL has a first mover advantage because it started the megamerger era and executed the DL/NW merger as flawlessly as any larger merger as any merger has taken place.
AA/US might be equally flawless and AA might well address its strategic weaknesses fairly quickly - and benefit from UA's weakness at the same time - but DL had at least a 7 year head start. The fact that DL is growing in Latin America at a 25% growth rate while also building out the west coast to Asia shows the capacity of a megacarrier to address the relatively small strategic deficiencies in their network..
And let's be clear that AA's need to balance its TATL network is relatively small in comparison to what it has to do in Asia.
And all of the growth that AA and DL are doing/will do is highly dependent on how quickly UA can get its act together. UA knows full well how much revenue it is losing to AA and DL and how the future of that company depends on getting their merger resolved and working.
As for FLL, DL is number 4 in passenger share behind B6, NK, and WN with about 14%. but in terms of revenue share, DL is #2 because the network carriers get higher average fares not only in FLL but in most markets where they compete with LCCs. DL's revenue share of the FLL local market is just under 17%. on a combined basis, AA/US' passenger revenue share at FLL is just over 12% while revenue share is at 15%.
Remember again that we have yet to see the affect of rationalizing AA/US combined network and DAL-FLL is one of the markets that WN will enter while DFW-FLL is one of AA's top markets.
