As discussed then already - I can't see them merging the programs.
The programs are so different, and local competition for the different StarAlliance-members is so different, the airlines and their frequent fliers would loose.
If the programs would merge, what do you think would become of the 'regional' specialities, like:[*]UA's (and AC's) North American upgrade vouchers (UA: 500 mile-upgrade-vouchers, confirmable one-way-NorthAmerican upgrade vouchers). UA (in competition with other major US-carriers on their local market), can't give up on these, all other *partners can't afford and have no interest in giving out such vouchers.[*]LH's upgrade on any fare rule. LH only introduced that rule in oct-17-1998 to better compete with other European carriers like Swissair (Qualiflyer) who also allow upgrades on any fare[*]The different (local, Inland-flight-) lounge-access rules. UA still want's to earn money for US-RCC access from NorthAmerican's and so do UA-s local competitors, European competition always offers free Lounge access for all status members and for all non status members travelling in business or first class.[*]the different miles needed for upgrades on different StarAlliance carriers. If the same amount of miles would be needed for first class-flights (award tickets or upgrades) on all *-carriers than nobody would choose UA on long-haule segments where UA competes with SQ.
