I appreciate that there is nothing comparable out there but that maybe US Airways has the programme that gets you further in terms of buying miles (with their frequent 100% bonus on purchased miles)? It'll take us a lot longer to buy our way to C class tickets for the family though... Would you agree with this in terms of burn rates per $?
