If you dumped BA because their agent gave you an inane answer about CAI, the bad news is that it seems that all the airlines' once-unimpeachable rtw desks seem to have made a home for the occasional twit. It's an unfortunate fact of life in the new millennium. (Caveat: I haven't had any bad experiences with Cathay.)

A machine-printed ticket might be more legible, should you encounter an agent somewhere along the way who wants to check the details to make sure you were charged properly for taxes and fees for leaving his domain. With airlines that don't have mechanical limits, it depends on the agent's skill in stringing together the text that goes in the additional-fees box. Get a recommendation for a TA who's willing to ticket you on CX or QF stock and you'll have no problem.
