The thing that I see is that e/n ticket classes have now replaced most of the lower cost tickets promos' .As Aviatrix said.. perhaps this is Ill advised KL staff uploading the wrong fare types onto fare classes ....
The fact that AF give all af ticket classes ( execpt some domestic things ) to earn miles , is this e/n thing only a stop gap ploy of FD to save a little bit of revenue untill the merger .
