I don't expect that it'll happen very much. How many pax will really go as far as blackmailing their TA just to have a lousy paper ticket over an e-ticket? The number of times that one might even conceivably be useful is pretty small, and most pax have taken the benefits of e-tix in their stride. And most TAs will just tell their pax that e-tix are now compulsory - you'd have to be pretty knowledgeable about the industry (and QF's policies) to be able to say to your TA "No, I don't believe what you've just told me about e-tix being compulsory; they're not, QF says they're not, and I demand a paper ticket."

BA have been charging a GBP 25 fee for a paper ticket on e-ticket routes since April, and even BA's "harshest critics" (according to BA themselves) have been pretty much silent on the issue. And before long BA intends to go over to "no paper tix at all".
