Let me tell you a big shocking secret. The integrated frequent flier schemes have in fact started to disintegrate because certain Star members are refusing to honour redemptions on certain others (go on guess which big American) becasuse they are so broke they either arne't paying the inter-carrier fees that have to change hands, typically a few hundred dollars for say turning UA
points to an SQ
ticket between Sydney and London, or they are being SO DAMN SLOW at doing it the redemptions are impossible.
Also as a person who pays for his own economy and business class tickets (and those of a few other people as well) the atrocious variation in quality among Star and oneworld carriers makes a mockery of their claims to be an association of excellence.
I get really peeved about advertising lies, and Star is one big con job.
If I've paid for my tickets I don't give a toss about priority this or priority that, because I'm a customer and if they don't give me what I paid for I go for them one way or another. Usually by persuading groups of old buggers like myself not to fly on the offending carriers.
Incidentally in Australia last time I looked the best RTW tickets were constructions made by suburban agents using consolidated coupons on both Star and oneworld carriers and for about $1000 less than on the net using Star only. Who the hell does Star think it is kidding?
