AC is especially complimented for its inflight entertainment and its free blanket (I thought the latter was charged to passengers in economy?!). Of course, one can argue that the IFE is not free, if the earphones/headsets are charged for economy class passengers - but then the counterargument is that the these earphones are re-usable, and nothing stops the passenger from bringing his/her own.
I think it would possibly increase transborder traffic if AC allows one free bag - many more people (at least US based) would go onto AC over US based carriers, if they go on transborder flights.
AC should think about introducing free wifi, whenever it introduces wifi fleet wide - possibly at least in business class.
