with delta I got most of the of my miles through the shopping program. In the end I redeem most of my miles for CO tickets since I live 20min from EWR and a hr from JFK. Soon I can't use skymiles on CO flights, so its time to leave Delta. CO's equivalent to the symilesshopping sucks, UA and US seem much better. - thats why

Can I use miles from other star alliance members on Qantas flights via CO?
