Thank you for the information. The fourth, and latest thread is most interesting.

I side with JohnAx when he says:

Not minding the wad of paper I have to stuff into a myriad of hotel safes (well, no more than 19 of them) I still see no benefit to the traveler of the electronic non-ticket.

A few months ago there was a thread here about the perils of e-ONE's in that there was quite a serious problem with one airline's computer not knowing you'd flown the previous segment, so what the heck were you doing trying to check in *here* (or something like that???).

I've had so many problems with the BA and AA computer systems not being able to "see" each other that I feel much safer with a paper ticket. It's also much easier to claim missing miles and q/tier points when you can provide physical evidence rather than relying on the vagaries of their computers, particularly BA's.
