My Experience flying into D.R. (Santo Domingo) two weeks ago on Spirit; no mention of E-ticket, however i was aware of it and attempted to complete it. I was unable to get very far because they ask for the town you are from as a drop box of options, you can't simply type in your town. Thus, my small town of 170 or so residents wasn't an option, apparantly we don't exist 😅🤣😆, that is why we are called "flyover country". I was surprised by the dropdown box approach, by doing it that way it appears they would need to input every single town in the world on the backside of the system.....which in my case didn't happen; so that was the end of trying to fill out the E-ticket. On the plane before landing their wasno talk of an E-ti ket and airline staff followed the traditional bit of handing out two forms to folks. Don't get me wrong, i have no problem completing an E-ticket even though I'm more of a "make a grocery list with pen and paper" type, but to think i would have been denied boarding because of that, until all the kinks are worked out, a policy like that would make for a lot of pissed off travelers..... i imagine it will improve over time but right now the E-ticket system needs to be bulked up to make its use a requirement.
