I think that DP (Doug Parker, not Double Penetration) needs to re-focus his efforts on completing the first integration and negotiating transition agreements with the respective workforces. By distracting himself with the Delta merger he is losing his focus and it could lead to his downfall.
Delta has made great strides in revamping its product, including introducing Richard Tyler-designed uniforms for the company's cabin crewmembers, upgrading its Business Elite cabins, ehancing the international service offerings in Economy (eye shades, menus, ear plugs, ptv's, etc), not to mention a significant expansion of its international presence across the globe.
Contrast this with Tempe, who has removed first class seats from the USAirways fleet, removed coat closets, lessened seat pitch, and altered Dividend Miles perks for the airline's most frequent customers.
From the perspective of a rather distant observer, I would hate to see Delta's image tarnished in the way that USAirways' image has been tarnished. Without any disrespect to the "Westies", America West was a second-rate carrier, both operationally and in the level of service offered. They have never been on par with with likes of American, Continental, or United. That's just a fact.
Additionally, I find it troubling that the new USAirways would go after a carrier that brings little to the table in terms of an expanded route presence. The mergers and acquistions that have been historically successful, are the ones that brought enhanced market presence to the acquiring carrier. The Delta-Western merger and the United-Pan Am route purchases, are very good examples.
Should the US-DL merger prevail...and I really hope it doesn't...my belief is that PHL and CLT (and possibly SLC) will be the most vulnerable cities to service cut-backs and work-force reductions during the next economic downturn.
In summary, I do not see the US-DL merger as an undertaking by a visionary mastermind. One only needs to look at the history of airline consolidation during the mid-to-late eighties, when, for the most part, employees, communities, customers, and stakeholders were left disillusioned by the fallout that resulted. (e.g. US-PS, US-PI, AA-OC, CO-FL-PE-NY).
That;s my two-cents, for what it's worth...
