Glad to see MH coming in to SkyTeam. Sooner the better. Their Southern Hemisphere (EZE-JNB/CPT) and SE Asian routes would plug a big whole in the ST Alliance, especially for RTW travellers presently stuck with jumping up to CDG/AMS/ICN.
Unfortunately, MH's entry to ST pretty much kills my dream of SQ or TG dumping * to fill the SE Asian whole in ST.
